Maximum audio sample frequency selected depending on the kind of connection used
Posted: Fri Jul 29, 2016 8:56 am
Reading the issues i just discovered that some renderers can have a specific maximum audio sample frequency hardware limitation for wireless connection and a different one for wired connection, like Naim Mu-So.
Certainly depending of the Wireless chip used: b,g,n,ac...
So the suggestion will be to add a variable in the renderer configuration that will permit to choose, for example, that when wireless connection is used the maximum audio sample frequency will be limited to a maximum of 48000 and not to the 192000 value defined for the wired connection.
Example :
Wireless --> 48khz
Wired (or by default) --> 192khz
That could be something like that :
Supported = f:wav n:2 s:192000 swired:48000 m:audio/wav
Not sure if it could be relevant though...

As for now when you build your renderer configuration, it's used indistincly of the connection kind.Audio Formats
WAV, FLAC and AIFF – up to 24bit/192kHz
ALAC (Apple Lossless) – up to 24bit/96kHz
MP3 – up to 48kHz, 320kbit (16 bit)
AAC – up to 48kHz, 320kbit (16bit)
OGG and WMA – up to 48kHz (16bit)
Bluetooth - SBC, AAC and aptX
Note: All formats to 48kHz maximum over wireless network
