High performance audio mixer

Aurora's sampled audio mixer creates high quality stereo output at up to 16-bit at 44KHz (CD-quality). The highly efficient mixer only uses 10% CPU on a 200 Mhz ARM processor mixing 8 channels into CD-quality output. Output speed can be reduced, or the output set to mono, to reduce the CPU load even more.

The mixer supports 32 virtual input sound channels, each with stereo panning, volume and pitch control. It also has master volume controls for music and sound effects.

Programming Interface

Aurora provides an object-oriented API with a consistent interface across all the supported audio devices and platforms. Its static library adds only 10K to Windows Mobile™ applications or 20K to Palm OS applications.

Audio source support

Samples may be loaded into Aurora from standard WAVE resources or Yamaha ADPCM format resources, and includes a utility to convert samples into ADPCM. Aurora loads in the ScreamTracker song format, allowing your application to include songs with up to 32 channels of wave-based music.
