| ) |
Returns an upsampler from a specified format to SPU2's native
- Parameters
-
freq frequency used bits bits per sample channels number of audio channels
- Returns
- a function to be used for upsampling, null if not found
Will return a function to convert source audio to Playstation's native. Note a very limited selection of upsamplers are available, only the most commonly used.
