Sonic Charge : BitSpeak Flashcards
Bitspeek is a …
real-time pitch-excited linear prediction codec effect.
Linear prediction coding is________that appeared in commercial products in the
____ and was implemented in some well-known ___ of the early
a voice compression technology
seventies
speaking toys
eighties
We have applied this technology ( Linear prediction coding) to create a VST / AU effect plug-in that ___audio, ____ a number of parameters (including pitch, volume and
formant data) and then ______ the audio using a simple____,
____ and ___ architecture.
analyzes
extracts
resynthesizes
oscillator
noise
filter
We have added a number of playback parameters that adjusts the___ and ___
quality of the sound as well as support for ____and a beat-synchronized “
_______”.
pitch
tonal
MIDI
“formant freezing effect”
Despite having only a few simple controls, this box can produce a broad range of sounds from cheap _____to high-end
_____and _____effects.

User Interface:
Rate (kHz):
Bitspeek performs its calculations at a _____ sample-rate, regardless of
_______. The possible settings are
(the last mode will actually adjust to the project sample rate and select a rate between ___).
designated fixed
the sample-rate your project is running at
8 kHz, 11 kHz, 22 kHz and 44 -> 48 kHz
44 and 48 kHz
Rate (kHz):Notice that Bitspeek is still compatble with any host sample-rate by performing _______. The Rate choice affects several other ____in the _____ and
changing Rate will ____
(Notice that the_____ mode
may require a lot of CPU. In many cases, the ___ mode works just as well.
automatic sample-rate conversion internal parameters DSP algorithms change the sound dramatically 44 kHz 22 kHz
Frame Rate:
The audio signal is _______ in blocks called “frames”
analyzed and processed
Frame Rate: For each
frame, Bitspeek estimates the ______of the incoming audio, as
well as the balance between _________.
pitch, volume and formants
“voiced” audio (e.g vowels) and
“voiceless” (e.g., the noise in a consonant)
Frame Rate: By _______, the analysis will be performed more rarely and you will achieve a cheaper toy-like sound.
lowering the frame rate
Frame Rate:
You can also “______” the
audio by dragging Frame Rate all the way down to___.
freeze
0
Frame Rate:
The parameter range is _____to___ (if Sync is ___)
0 to
80 Hz
off
Frame Rate:
higher rates requires more ____ than lower rates.
CPU
Sync:
Enable Sync to make Bitspeek ____ in sync with the tempo of your music.
“freeze” frames
Sync: When Sync is enabled, you may select various___with the Frame Rate slider instead of selecting a rate in ___
time synchronized rates (1/8, 1/16 etc)
Hz
MIDI:
Enable MIDI to control the ___and___ of the effect via MIDI.
pitch and envelope
MIDI:
You will need a
host that is capable of _____ to effect plug-ins in order to use this feature. Please ______for your host for information on how to set it
up.
transmitting MIDI
read the documentation
MIDI:
When enabled, Bitspeek will play only when it _____ and it will transpose_____ according to the MIDI notes it receives.

MIDI:
Turn down the_____
to ____ to achieve a vocoder / auto-tune like sound.
Tracking parameter

MIDI:
If you set the ____(with____ disabled), Bitspeek will “freeze” the formants on MIDI____ allowing you to create interesting “stroboscopic” audio effects.

Finally, Bitspeek supports
Pitch Wheel messages (one ________and____) and the MIDI Sustain Pedal can
also be used to_____while playing
(one octave up and down)
