Comment:
The constraints that Kalle Rutanen used to derive these conversions are
not actually requirements of !PulseAudio.
In the original field, real-time graphics, integer values are usually
quantized to 8 bits, and filters can be applied repeatedly to the same
bitmap. Audio samples have higher precision (16 or nowadays mostly 24
bits), and conversions are not done repeatedly, so I would estimate that
numerical stability or bijectivity are not important at all.
Are there specific quality problems in !PulseAudio's output that would be
avoided by these conversions?
