DAC distortion. Interesting video - Donuk - 09-09-2026 17:22
I found this on Youtube.

Is there any way of reducing the modulation of the digital signal by 3db as it leaves Minim before it reaches the DAC of one's streamer?
Sorry if a stupid question.

You can do this by using MinimStreamer transcoding with the stream.options property set to this value:
convOut=-af volume=-3dB

Wow! Brilliant - must give it a try!

So, I have tried it!
I put in the above code into Minim using Minimwatch.
I rebooted my old Melco N/1A which contains the Minim software. It needed time for a quick rescan.
I rebooted my Linn Klimax DS (old style with organic) for luck.
And listened to some tracks I know well.
And it all sounded better. Not day and night, but better.
Instruments sounded more separated; things sound slightly clearer, but not brighter. And bass sounds a bit deeper without being louder.
I had been prepared the whole to be a bit reduced in volume but this appears not to be the case.
Do try it on your system - you never know, you might have an upgrade for free thanks to good old Minim.
Satisfied customer, York.

When you tried this, what setting did you have for stream.transcode?
Before you tried this, were you using MinimStreamer transcoding with the same stream.transcode setting?
RE: DAC distortion. Interesting video - Donuk - 10-09-2026 19:53
I had nothing in the stream option property settings.
Then I put in the settings you gave above.

My question was about the stream.transcode property. If this isn't set, there is no transcoding and no volume reduction. My apologies for not making this clear in my original response.

Sorry to be thick…
But what should I put in as stream.transcode property?
Something like *:wav?
Donuk
RE: DAC distortion. Interesting video - simoncn - 11-09-2026 11:53
You shouldn't use *:wav because the * means 'network streams of unspecified type.'
If you have flac files, you should use use flac:wav; or flac:wav24; (the semicolon is important). If you have mp3 files, you should use mp3:wav or mp3:wav24. If you have m4a or mp4 files, you should use mp4:wav or mp4:wav24. For a full list of supported filetypes, see this section.
If you have a mix of filetypes, use multiple settings separated by commas, for example:
flac:wav24;, mp3:wav24, mp4:wav24
