[Audacity-devel] Plug - in Creation in Audacity .

[aishwarya selvaraj]

Hi Everyone ,

Myself Aishwarya , ​a Researcher from India working on Speech Signal
Processing .
I have developed a Time/Pitch Scaling Algorithm .I have the corresponding
.cpp script and matlab code for the same .I want to include my version of
pitch/time scaling into Audacity .
I wanted to know how to create my own plugin in Audacity .
Is it possible ?Can anyone guide me ?

Hoping for reply.

Hi Aishwarya,

As I asked you on the -users list, can you describe the algorithm and how
it differs from SBSMS which is currently used in Sliding Time Scale /
Pitch Shift?

Also here again is one of the links I gave you before:

Thanks.

Hi Aishwarya,

Is there a working version of your code available?
Could you tell us a bit about the algorithm.

Currently Audacity has two algorithms available for time/pitch
scaling. The default algorithm for the "Change Pitch" and "Change
Tempo" effects is provided by libsoundtouch
(http://www.surina.net/soundtouch/). The algorithm used by "Sliding
Time Scale / Pitch Shift", and (new in Audacity 2.1.3) as an option in
"Change Pitch" and "Change Tempo", is provided by SBSMS
(http://sbsms.sourceforge.net/). How does your algorithm compare with
/ differ from these algorithms?

Audacity supports several plug-in formats.

On all platforms:
Nyquist (http://wiki.audacityteam.org/wiki/Nyquist_Plug-ins_Reference),
LADSPA (https://en.wikipedia.org/wiki/LADSPA), VST, and "built-in"
effects (mostly in C++).
Note that Nyquist plug-ins are fully cross-platform whereas LADSPA and
VST plug-ins require platform specific builds.

On Mac OS X, AU plug-ins are also supported
(https://developer.apple.com/library/content/documentation/MusicAudio/Conceptual/AudioUnitProgrammingGuide/Introduction/Introduction.html)

On Linux, LV2 effects are (partially) supported (http://lv2plug.in/)
(Audacity theoretically supports LV2 on all platforms, but I don't
know of any LV2 plug-ins for Windows or OS X)
