ReplayGain

Thanks for this feedback and all the useful suggestions.

I have always been doubtful about implementing this as a server-side feature. If the correct gain setting depends on whether the control point is using "shuffle (album)" mode or "shuffle (track)" mode, this implies that the control point (and possibly the renderer) need to be involved in selecting the correct gain setting.

In terms of when the gain adjustment is applied, if this is done as part of MinimStreamer ffmpeg transcoding, it would need to be applied to the input stream before this is upsampled or downsampled to produce the output stream. For example, if the input stream is 16 bits and the output stream is 24 bits, the gain adjustment would be applied to the 16-bit stream.

My conclusion is that the relatively simple server-side implementation that I had been considering would not meet the needs of users who want this feature. A player such as foobar2000 can provide a full-featured implementation because it provides the complete end-to-end serving/controlling/transcoding/rendering chain and this is the best option for users who require this functionality.
