Is the Finch audio library for iPhone capable of doing this?

I need to:

- start / stop sounds with lengths between 0.1 and 10 seconds
- change the playback volume

I want to / would like to / would be nice to have to:

- change the playback speed
- change the p开发者_运维知识库layback pitch / frequency
- pause an sound and resume playing it later
- play a sound backwards

Is Finch my best friend here?

The current version can do everything you want except changing the playback speed independently on the pitch (playing sound faster increases pitch) and playing sound backwards.
