| Chorus2 Audio Support Readme |
| ============================ |
| |
| Audio support for Chorus2 uses the ALSA SoC Audio framework (ASOC). |
| |
| Supported Data Formats |
| ====================== |
| Signed 16bit Little Endian (left and right Data Packed to 32bit frame) |
| Signed 24bit Little Endian (Data left justified to fit 32bit frame). |
| |
| Supported Sample Rates |
| ====================== |
| 32000 (32KHz) |
| 48000 (48KHz) |
| 64000 (64KHz) |
| 96000 (96KHz) |
| |
| Development Status |
| ================== |
| Only Playback has been implemented. |
| Testing performed on ATP-DP (Metamorph) base layer only (Line Out). |
| Playback of PCM Data (in .pcm and .wav formats) is working for all supported |
| sample rates and formats. |
| Playback via aplay and madplay / mplayer has been tested. |
| Note: mpg123 or apps using libmpg do not play due to the use of floating point, |
| use libmad(madplay) instead as this uses fixed point maths instead. |
| |
| Further Work |
| ============= |
| Add support for ATP-DP-Audio (audio Layer) 4 x stereo channels |
| Add SPDIF Output support. |
| Add SPDIF Input support. |
| Add I2S Audio In Support. |
