# stretchplayer(1)

Audio player with time stretch and pitch shift

## NAME

stretchplayer - Audio player with time stretch and pitch shift

## SYNOPSIS

**stretchplayer** \[file\]

## DESCRIPTION

StretchPlayer is an audio file player that allows you to change the speed of  the song without changing the pitch. It will also allow you to transpose the  song to another key (while also changing the speed). This is a very powerful  tool for musicians who are learning to play a pre-recorded song. Its features  include:

- •

  Time Stretch (50% to 150% of song speed, without changing pitch)

- •

  Pitch shift (up or down 1 octave)

- •

  A/B repeat

- •

  Lots of keyboard accelerators

The player supports all the audio formats that libsndfile supports, which  currently includes OGG/Vorbis, WAV, W64, AIFF, SND, and FLAC. Note that  neither libsndfile nor StretchPlayer supports MP3 files for patent liability  reasons.

## BUGS

StretchPlayer will not work if you have a small buffer size (\<= 256 frames). Bug reports can be sent to gabriel@teuton.org.
