SONIC(1) General Commands Manual SONIC(1)NAME
sonic - Speech speed manipulator
SYNOPSIS
sonic [OPTION]... inFile outFile
DESCRIPTION
Sonic is used to make wav files of speech faster or slower. The primary advance in sonic is the ability to speed speech up by much more
than 2X, with minimal distortion. However, sonic can be used for both speeding up and slowing down speech files. Additionally, sonic can
change the pitch and volume.
OPTIONS -c Modify pitch by emulating vocal chords vibrating faster or slower. This causes more distortion than the default pitch scaling, but
sounds more like the same person trying to talk higher or lower. The default pitch changes makes the voice sound like a larger or
smaller person, but introduces little distortion.
-p pitch
Set pitch scaling factor. 1.3 means 30%% higher.
-q Disable all speed-up heuristics, possibly improving the quality slightly. This is mainly used for debugging the speed-up heuris-
tics.
-r rate
Adjust the speed of playback. This sales both the pitch and speed equally.
-s speed
Set speed up factor. 1.0 means no change, 2.0 means 2X faster.
-v scaleFactor
Scale volume by scaleFactor. 1.5 increases by 50%. Clips if the maximum range is exceeded.
EXAMPLES
sonic -s 3.2 book.wav book_fast.wav
The above command would increase the speed of an audio book called book.wav by a factor of 3.2, and write the result in book_fast.wav.
sonic -s 0.5 -v 1.5 spanish.wav spanish_slow.wav
This would slow down the file spanish.wav by a factor of 2, make the volume 50% louder, and write the result to spanish_slow.wav.
sonic -p 2.0 low.wav high.wav
This would make a low voice sound very high pitched.

CONVERT4CHAN(1) convert4chan Manual Page CONVERT4CHAN(1)NAME
convert4chan - is a utility for converting pairs of stereo impulse response files to to a single 'True Stereo' 4-channel files.
ir.lv2 - LV2 IR reverb plugin supports these so-called 'True Stereo' impulses.
USAGE
convert4chan /path/to/impulses/directory
or
cd /path/to/impulses/directory and run convert4chan
DESCRIPTION
convert4chan is not itself a generally useful program, but just a utility with very limited scope, Error checking is limited; you are not
supposed to run convert4chan on your / .
You can use it to convert a full directory tree of stereo impulse response files with similar names that end with L.wav and R.wav to 'True
Stereo' format, while your original files in directory stay untouched and can be later used as impulses as well.
'True Stereo' impulses are four channel impulses that describe a full convolution matrix (the four channels contain, in order, the convolu-
tion paths L->L, L->R, R->L, R->R).
convert4chan searching for stereo files named:
root/somewhere/somethingL.wav
root/somewhere/somethingR.wav
and convert them to:
root/somewhere/something4.wav
convert4chan supports filenames ending in .wav by design, but it is possible that in future will supports other audio formats too (It could
all audio formats supported by libsndfile in theory.)
More information can be found on the project website http://factorial.hu/plugins/lv2/ir.
