Detailed Description

An audio asset, using any supported compression codec.

stir generates an AssetAudio for each sound element in your assets.lua configuration file, most often from a WAV source file.

See the Audio and Asset Workflow guides for details.

Member Function Documentation

static AssetAudio Sifteo::AssetAudio::fromPCM ( const int16_t *  samples, unsigned  numSamples  )

inlinestatic

Create an AssetAudio object programmatically, from uncompressed PCM data.

This creates an AssetAudio instance which references the specified buffer of 16-bit uncompressed PCM samples. You can use this to wrap dynamically synthesized audio data for playback on an AudioChannel.

This is intended mostly for creating software "instruments" for real-time audio synthesis, so we default to looping mode, and there is no default sample rate or volume. These parameters can all be set via AudioChannel at runtime.

unsigned Sifteo::AssetAudio::speed ( ) const

inline

Return the default speed for this audio asset, in samples per second.

This can be used to calculate a new speed for AudioChannel::setSpeed().
