FL Manual 15 Compress/Convolver/Delay 2 3 Flashcards
FL STUDIO - Fruity 7 Band EQ
What is Fruity 7 Band EQ?
- Fruity 7 Band EQ is a seven-band (one low shelf, one high shelf and five peaking) equalizer plugin, optimized for low CPU use.
- -It is a close cousin of Fruity Parametric EQ 2, which provides greater control.
- –Fruity 7 Band EQ has seven tone controls with slightly overlapping frequency ranges.
- —Disable the bands (set the level to 0) to save CPU processing.
FL STUDIO - Fruity Balance
What is Fruity Balance?
- Fruity Balance is a stereo balance plugin, optimized for real-time level automation.
- -This is a true panning effect, it works by mixing left and right channels so that the left and right stereo channel information are no longer independent when panned.
- –It’s the audio equivalent of starting with two glasses with the same water level in each (balanced) and then pouring one glass into the other (the contents are mixed).
- —The alternative approach is to vary the relative loudness of the left and right channels to create a panning effect while maintaining the independence of the channels. An alternative is Stereo Shaper.
FL STUDIO - Fruity Bass Boost
What is Fruity Bass Boost?
-Fruity Bass Boost is a bass enhancing effect (specialized EQ).
Parameters:
–Frequency - Adjusts the frequency range to be boosted.
—Amount - Sets the effect strength.
FL STUDIO - Fruity Big Clock
What is Fruity Big Clock
- It shows the playing time in Bar:Beat:Tick format and Minute:Second:1/100 format.
- -Optionally, it can also display the song time in Bar:Step:Tick format.
- –To use, just drop an instance of the plugin on any Mixer track
FL STUDIO - Fruity Blood Overdrive
Pre Band Knob
- Sets the amount of low-pass filtering that is applied to the audio before it is overdriven.
- -Use this to remove high frequencies that may result from over driving audio with a broad frequency range.
FL STUDIO - Fruity Blood Overdrive
Color Knob
-Sets the frequency cutoff for the Pre Band filtering.
FL STUDIO - Fruity Blood Overdrive
Pre Amp Knob
- Overdrives the audio in order to achieve distortion.
- -As you increase the ‘Pre Amp’ parameter, you need to compensate with the Post Gain knob.
FL STUDIO - Fruity Blood Overdrive
x100
- Increases the power of Pre Amp level 100x.
- -This is normally only useful on single instrument inputs.
FL STUDIO - Fruity Blood Overdrive
Post Filter
- The pre amplified audio is low-pass filtered at the frequency specified by this knob.
- -This is another option for cleaning up the distortion.
FL STUDIO - Fruity Blood Overdrive
Post Gain
- Final gain reducer (at maximum leaves the gain at its original level after distortion).
- -The preamplifier boosts the output considerably, so you need to compensate with this parameter
FL STUDIO - Fruity Blood Overdrive
Audio signal flow through the plugin is
-Band Pass Filter (Pre Band) > Preamplifier (Pre Amp) > 2-Pole Low Pass Filter (Post Filter) > Reduce Gain (Post Gain) > FinalDigital Clipping.
FL STUDIO - Fruity Blood Overdrive
Playing a mix through the plugin, (even without pre-amplifying), causes what?
- Upward compression on the independent frequency bands.
- -This gives overall upward compression and flattens the equalizer.
- –This can be used to improve some mixes,and can even be used to master some projects (the compression is caused by non-linear signal response similar to ‘vacuum tube’ compressors).
FL STUDIO - Fruity Center
What is Fruity Center?
- Fruity Center removes DC offsets in real-time and is useful for synthesizers which generate DC offsets.
- -The term DC offset comes from electronic engineering, and refers to the situation where a Direct Current (DC) exists, that is a constant positive or negative deflection in the output from a plugin, rather than being at rest (zero) when no sound is present.
- –This can cause problems as the waveform will oscillate around this ‘offset’ center and so have reduced headroom on the side of the DC offset bias.
FL STUDIO - Fruity Chorus
What is Fruity Chorus?
- Fruity Chorus is an effect created by the slight detuning of one or more delayed copies of the input sound (similar to a choir of voices).
- -Controls adjust the rate, time offset, shape and depth of detune.
FL STUDIO - Fruity Chorus - Parameters
Delay
- Sets the minimum delay between the chorus voices.
- -The chorus delay will be swept between delay and delay+depth.
- –Range: 0 to 30 milliseconds. For ‘deep’ chorus effect, set this parameter to low values.
FL STUDIO - Fruity Chorus - Parameters
Depth
- Controls the chorus delay modulation.
- -The chorus delay will be swept between delay and delay+depth. If this value is zero, the chorus will remain ‘static’ as the delay modulation will stay constant.
- –Setting the ‘Depth’ to higher values will create heavier modulation.
FL STUDIO - Fruity Chorus - Parameters
Stereo
- Controls widening of the stereo image.
- -If set to 0, the LFO on the left and right channel will be in perfect synchronization.
- –At 180 degrees the left and right channel will be 100% out of phase, i.e. left channel will reach maximum when right channel is at minimum.
- —Range: 0 to 360 degrees. Try setting 10 degrees for subtle stereo enhancement.
FL STUDIO - Fruity Chorus - Parameters
LFO 1 Freq / LFO 2 Freq / LFO 3 Freq
-Sets LFO modulation speed.
FL STUDIO - Fruity Chorus - Parameters
LFO 1 Wave / LFO 2 Wave / LFO 3 Wave
-Waveform of the LFO. Multi-sine is a mix of a normal sine wave and one three times its speed.
FL STUDIO - Fruity Chorus - Parameters
Cross Type
- Defines whether the plugin works on the lower or higher frequency part of the signal.
- -Process HP processes only high frequencies, Process LP processes only low frequencies.
FL STUDIO - Fruity Chorus - Parameters
Cross Cutoff
-Cutoff frequency of the cross-over filter.
FL STUDIO - Fruity Chorus - Parameters
Wet Only
-If using the chorus as a send effect, switch this parameter to mix the pure ‘wet’ output with the source sound.
FL STUDIO - Fruity Compressor
What is Fruity Compressor?
-Fruity Compressor is a legacy plugin, we recommend Fruity Limiter which also has a flexible compressor section.
FL STUDIO - Fruity Compressor - Parameters
Type
- Controls the knee type and TCR.
- -The possible values are: Hard, Medium, Vintage, Soft, Hard/R, Medium/R, Vintage/R, Soft/R.
- –The knee determines the dB range, above and below the threshold, in which the compression changes from 1:1 to the selected compression ratio.
- —A hard knee setting means that compression will take place immediately after the threshold level is reached, whereas a soft knee setting indicates that compression is gradually applied over a range in the signal.
FL STUDIO - Fruity Compressor - Parameters
What does Knee Determine?
-The knee determines the dB range, above and below the threshold, in which the compression changes from 1:1 to the selected compression ratio.
FL STUDIO - Fruity Compressor - Parameters
Report latency
- Reports processing latency to FL Studio for PDC.
- -This option is provided for compatibility with projects prior to FL Studio 20, where latency for Fruity Compressor was not compensated.
- –If PDC makes old projects sound different, in a bad way, deselect this option and reject the future! Normally, you should leave this option selected.
FL STUDIO - Fruity Compressor
Knee Type
- While attack controls the speed with which compression is applied, the compressor’s knee characteristics control the rate at which compression is applied.
- -Soft means there is a gradual increase from no to full compression as the input volume increases, while hard means the transition from no to full compression is instant once a predefined input level is exceeded.
FL STUDIO - Fruity Compressor - Parameters
Knee Type
The actual values for this property mean:
Hard
Medium
Vintage
Soft
Hard - 0 dB
Medium - 6 dB
Vintage - 7 dB
Soft - 15 dB
FL STUDIO - Fruity Compressor - Parameters
Knee Type Vintage
- The Vintage compression type emulates the compression curve found on some analog compressors, such as the classic Teletronix LA2A.
- -The major difference is that the compression ratio is gradually reduced at a distance above threshold, slowly allowing the level to go back to a ratio of 1:1.
- –This allows the loudest parts of the signal, such as drum beats and other peaks, to pass without being compressed as much as the rest of the signal.
- —In this way, the Vintage compression type emulates electro-optical analog designs and can greatly enhance warmth and ‘punch’.
- —-The Vintage compression type also affects the TCR parameter, utilizing a different release time adjustment method.
FL STUDIO - Fruity Compressor - Parameters
Knee Type
The R types enable TCR (Transient Controlled Release),
This is/does what?
- A special algorithm that automatically adjusts the release time in real-time to avoid fast compression changes.
- -The release time is adjusted in relation to the current Release parameter setting.
- –Enabling TCR can have positive effects on some types of audio material, and help to reduce “pumping and breathing”, while increasing the overall loudness of the signal.
FL STUDIO - Fruity Convolver (Convolution, Convolution Reverb & Linear Phase EQ)
What is Fruity Convolver (Convolution, Convolution Reverb & Linear Phase EQ)?
- Fruity Convolver is a real-time Convolution plugin that can be used to add reverberation, create special effects, apply an acoustic impulse (audio signature) captured from audio equipment/plugins or perform as a linear phase equalizer.
- -When convolving, Fruity Convolver applies the sonic character of one sound to another by convolution of the input audio with an impulse response.
FL STUDIO - Fruity Convolver (Convolution, Convolution Reverb & Linear Phase EQ)
Describe the Convolution Process
- The convolution process basically triggers playback of the whole impulse response file, for every sample of the audio input.
- -With the added complication, the level of the impulse response is multiplied by the value of the input sample (-1 to +1).
- –In other words, if the input audio is a single click, 1 sample at 100%, then you will hear the original impulse response.
- –If the impulse response is a single 100% click 5 seconds after the start of the file, you will hear an echo of the input audio delayed by 5 seconds.
- —It’s similar to playing an audio recording, on a keyboard, triggering it for every sample of the input waveform, at the value of the triggering sample (note velocity).
FL STUDIO - Fruity Convolver (Convolution, Convolution Reverb & Linear Phase EQ)
What is Convolution used for?
- Most commonly convolution is used to reproduce the reverberation captured from real acoustic spaces you wouldn’t normally have the opportunity to record in, or expensive/rare hardware reverb units.
- -It’s also possible to capture an impulse response through a guitar amplifier, from a speaker, microphone or to use any interesting audio file as an impulse response to create weird effects.
- –The process of making impulse responses is discussed in the section ‘Making your own impulses’ at the bottom of this page.
FL STUDIO - Fruity Convolver (Convolution, Convolution Reverb & Linear Phase EQ)
NOTE: Any audio file can serve as an impulse, experimentation will reward you with unique and interesting sounds.
FL STUDIO - Fruity Convolver (Convolution, Convolution Reverb & Linear Phase EQ)
Options, There are two main areas on the plugin interface, which are?
–The knobs along the top of the plugin give access to commonly used controls and the lower ‘Editor’ window that can be switched between impulse, the impulse can be manipulated like any recorded audio, and equalizer that can apply equalization to the impulse.
FL STUDIO - Fruity Convolver (Convolution, Convolution Reverb & Linear Phase EQ)
Dry Knob
Dry Adjusts the level of the dry signal (0 to 100%).
FL STUDIO - Fruity Convolver (Convolution, Convolution Reverb & Linear Phase EQ)
In Knob
-Input stereo separation Turn left to maximize stereo separation of the input or right to create a mono input.
FL STUDIO - Fruity Convolver (Convolution, Convolution Reverb & Linear Phase EQ)
Wet Knob
Wet Adjusts the level of the wet signal (reverb / convolution) sound (0 to 100%).
FL STUDIO - Fruity Convolver (Convolution, Convolution Reverb & Linear Phase EQ)
Normalize Loudness normalization. This is useful to maintain a consistency across impulses as there can be dramatic differences in gain between them.
FL STUDIO - Fruity Convolver (Convolution, Convolution Reverb & Linear Phase EQ)
Wet stereo separation Enhance or reduce what?
stereo effect in the wet output
FL STUDIO - Fruity Convolver (Convolution, Convolution Reverb & Linear Phase EQ)
Delay
- Adds a delay to the first reflection from the impulse.
- -NOTE: Many reverb impulses have a period of silence at the start, the time taken for the sound to reflect off the closest surface to the microphone/s. Fruity Convolver will detect these delays and use the (delay) time to lower CPU load.
FL STUDIO - Fruity Convolver (Convolution, Convolution Reverb & Linear Phase EQ)
Self-conv
- The impulse is convolved with itself before being convolved with the input.
- -This creates a similar effect to putting a reverb on the impulse.
FL STUDIO - Fruity Convolver (Convolution, Convolution Reverb & Linear Phase EQ)
Stretch
- Uses high quality resampling to change the length & pitch of the impulse.
- -NOTE: This is not time stretching so the frequency of the impulse response is shifted lower with stretching and higher with time-compression.
- –It usually sounds right, unlike time-stretching on the impulse with constant pitch from the editor functions that often results in phasing artifacts.
FL STUDIO - Fruity Convolver (Convolution, Convolution Reverb & Linear Phase EQ)
Eq
-Balance between the Equalized and Normal impulse response.
FL STUDIO - Fruity Convolver (Convolution, Convolution Reverb & Linear Phase EQ)
KB Input
-Select to enable keyboard shortcuts in the impulse & EQ editors.
FL STUDIO - Fruity Convolver (Convolution, Convolution Reverb & Linear Phase EQ)
Updating
- Animates while the plugin is processing changes to settings.
- -There may be a short period of silence when the convolution algorithm updates.
- –Note: Don’t touch the Delay, Stretch, Self convolve or Eq controls if an interruption to the sound will be an issue (during live performance for example).
FL STUDIO - Fruity Convolver (Convolution, Convolution Reverb & Linear Phase EQ)

-Alternatively click the disk icon and use the Windows file browser to locate your own impulse responses.
–Envelopes Several standard envelope controls are accessible along the bottom of the window that act on the Impulse sound. From left to right -
Pan To edit the Pan envelope.
-Volume To edit the Volume envelope.
–Stereo Separation To edit the Stereo Separation envelope.
—All-purpose envelope Can be assigned to playback velocity/direction and various other functions.
FL STUDIO - Fruity Convolver (Convolution, Convolution Reverb & Linear Phase EQ)
Editing envelopes
- After selecting the desired envelope type, Right-click in the ‘Impulse Editor Window’ to add points, and Left-click to move points and tension markers.
- -Right-click points to open a context menu that will allow you to delete points or change the curve type.
FL STUDIO - Fruity Convolver (Convolution, Convolution Reverb & Linear Phase EQ) Trigger impulse (spark icon)
Click this icon to create a ‘click’ impulse to create impulses from plugin effects (see a video tutorial here):
1. Load two instances of Fruity Convolved in the FX slots above and below the effect to be captured.
2. Make sure the plugin has a fairly loud dry signal passing through so the recording Fruity Convolver can reliably detect the onset of the impulse sound. This is used to compute predelay.
3. Press the record button on the lower Fruity Convolver that will perform the impulse recording.
4. Press the Trigger impulse control. The recording Fruity Convolver will capture the impulse until the signal level falls to zero and automatically stop.
To make impulses from external hardware devices we recommend using the Sine-wave sweep method discussed below. Although in this case you can record the sine-wave sweep as it is played through the equipment, no need for microphone rigs.
FL STUDIO - Fruity Convolver (Convolution, Convolution Reverb & Linear Phase EQ)
Plugin Delay Compensation (PDC)
- The Latency icon (), just above the Editor window, can be used to manually set the latency Fruity Convolver reports to FL Studio.
- -This is useful where impulses impose significant delay on the dry signal, such as with the Linear phase EQ impulses.
FL STUDIO - Fruity Convolver (Convolution, Convolution Reverb & Linear Phase EQ)
Impulse Equalizer Window
- The equalizer functions acts on the impulse itself, not directly on the audio passing through the plugin, so the effect is to change the EQ of the convolved part of the output.
- -You can also use this section to perform Linear phase EQ (see below).
- –The background display shows a frequency spectrograph with time on the vertical axis (time zero is at the top) and frequency on the horizontal axis (frequency is indicated in Hz and Octaves along the bottom of the display). The EQ can be useful to fine-tune impulse responses that don’t have the desired tonal characteristics. Pops & claps often excite the mid-range frequencies more strongly than the low and high frequencies. A gentle U shaped curve can help restore a more pleasing frequency balance.
