To add a sound file, the easiest way is to drag’n’drop it either from the operating system, or from the library.
ossia score supports 4 modes of playback:
- No stretching at all (Raw).
- Re-pitching through resampling thanks to the libsamplerate library.
- Time-stretching (pitch does not change) thanks to the Rubberband library, in a mode optimized for drums and another for tonal instruments.
If a file has any tempo information (either through ACID tags or a BPM present in the filename), it is automatically assumed to be a loop and put in loop mode with the timestretch enabled.
The tempo of the soundfile can be adjusted through the inspector ; the ratio between its tempo and the current playback tempo will be used to timestretch / repitch accordingly.
score will stream .wav / .aiff files at the same samplerate than the project from disk directly. All the other files will be decoded first and read from RAM.
- Until a choice is implemented, we recommend users who have large .wav files and slow hard drives to set-up a RAMDisk manually.
score should be able to read any file supported by FFMPEG. Current releases are built with FFMPEG 4.4. The list of supported audio format is available here.
