Audio Streaming
under construction...to be continued...
History
Audio Streaming refers to a data type found in certain GameCube titles which is used for the playback of music, voices, or sound FX. When this data is requested to be used, the DVD drive is commanded to read a designated disc offset length for ADPCM audio data which is converted within the DVD drive's hardware into PCM audio. This converted PCM audio is then relayed to the DSP to be resampled and mixed with any other audio which may be playing. The common practice of using multi-title discs required shrinking the physical length of the title which also broke 32kbyte alignment and resulted in DVD reads from an incorrect offset.
Confusion
GameCube mod chips utilized a feature which corrected streaming audio on backup media labelled "GameCube Audio Fix". This was performed via IPL replacement such as Viper and qoob, or by patching the dvd drive with a drive chips such as XenoGC. Without this games would try to read internally from an incorrect offset, and although the game wouldn't report a read error, there was static instead of audio.
Wii initial modchips (drive chips) provided the same fix as the GameCube modchips did, Wiikey V1 and perhaps V2 even had this.
Then the Wii DVD drives locked modchips out slightly so the only solution was to intercept read commands between the DVD and the Wii and turn them into DVD-Video requests, at this point, any kind of Audio Streaming fix was thrown out the door. Because of this, Audio streaming games would throw read errors and/or play static instead of actual audio.
Modchip manufactures started using descriptions such as "GameCube Audio Fix" with a new meaning now. these modchips only disabled the streaming audio data to prevent read errors and/or static sound instead of providing a true ability to read the stream data correctly.
Solutions
solutions to play these titles depend on method media or modchip being used.
Gamecube Modchips
all native gamecube modchips work to play audio streaming titles from dvd disc.
Wii Modchips
wii drive replacement modchips usable on gamecube such as wkf/wode will be affected by audio streaming titles due to the design on the modchip and how it disables the audio streaming data from reaching the motherboard correctly...blah blah...currently WKF and WODE are not able to send audio streaming data to the gamecube using SD, HDD, USB media respectively.
to regain ability to correctly play these audio streaming titles with a drive replacement modchip, a dvd drive must be utilized in conjunction with the modchip in bypass (flat) mode....or using swiss to boot a dvd
| WKF | WODE | |
|---|---|---|
| original disc | wire mod | nothing |
| backup disc | xenoGC + wire mod | xenoGC |
- note: IPL replacement modchips (viper/qoop) may fail to detect these drive replacement modchips and not recommended for use
and blah blah
these work around mods are the only solutions available to for wkf/wode
