Sample Rate, Bit Depth and Channels

[urielz]

I haven't found a way to access the sample rate, bit depth and channels of a song in QL. Is there a way to do that? It would be useful to add these variables as internal numeric tags.

currently not, but mutagen reads/parses that information in most cases.

Why do you need it?

[urielz]

No real need. My collection is in FLAC with various sampling rates/bit-depths. It would just be nice to have that information at hand and be able to filter/search it.

Potentially audiophiles would find it useful as sometimes they have the same album in different formats (CD, SACD, etc) and the best way to differentiate them would be by looking at the sample rate and bit-depth.

FWIW I find that ~#bitrate is a good enough substitute (for me), even though it conflates all these variables (arguably in a useful way)

[lazka]

While I don't find it that useful either the only downside is memory usage, and that's not that big of a problem nowadays.

Somewhat related: Latest mutagen also can read the lame version and guess if it is VBR/ABR/CBR, maybe add a "~codec" for that?

It would be great to have this, bitrate isn't very relevant for lossless files.
IMO the best would be to have ~channels, ~bitdepth and ~samplerate or something like that, instead of one internal tag for all. However I don't know if it's difficult to implement.

720b339 added ~#channels

[lazka]

#2872 added ~#bitdepth and ~#samplerate

[urielz]

Thanks @lazka for making this happen! This is awesome :)

[Hunter16g]

Thank you !
I've tried adding <~#samplerate> and <~#bitdepth> in the display, but it doesn't return anything. Am I doing something wrong ? The files are in FLAC, quodlibet version is 4.2 development 6ba95ed

@Hunter16g thanks for the report, I've added flac support in 15e7dc0
