Feature Request: Resampling for low quality ONLY
« on: August 16, 2011, 05:16:38 pm »

Could really use a resampling option that resampled sources less than 44.1KHz ONLY.  My DAC won't accept some of my audiobooks sampled at 22KHz, but I don't want J River resampling my 176KHz hi res stuff.

I agree, it's a good idea.  We'll try to add this soon.  If it isn't done in two weeks, please bump this thread to remind us.

And welcome to Interact.

Coming in 16.0.154 (and later):
NEW: Added DSP Studio > Output Format resampling mode 'Only sources less than 44,100 Hz'.

Matt this is a good change as I too have Video Files some of which have low audio sample rate stuff typically recorded by cheap camcorders including rates such as:
- 7,875Hz in mov
- 16,000Hz in wmv
- 22,050Hz in wmv and AVI
- 32,000Hz in wmv and mpg


The reason I like it is I "almost" provides a "Resample to next support sample rate" so that I could only resample stuff my Audio Card did not like (I currently resample everyting to 96,000hz).  Then I though, Mmmmm what if there are other unsupported sample rates above 44.1Khz (this new option would fail).  It looking at my library I did find plenty of stuff with "std" rates (44,100Hz 48,000Hz 96,000Hz 192,000Hz), but I did see some odd reported sample rates:
- 1,00Hz in mp4  - but it really is 48,000Hz
- 131,073Hz in DV-AVI - but it really is 48,000Hz
- 131,089Hz in AVI - but it really is 48,000Hz
- 157,553Hz in MKB - but it really is 48,000Hz
- 393,217Hz in MKV - but it really is 48,000Hz

So two things:
- The parser/splitter used in these cases is just missreporting the sample rate (so playback works fine) and
- Is there any "non" std sample rates above 44.1KHz that will cause playback to fail on std audio card?

The multiples of 44,100 are not supported everywhere - 88,200 and 176,400.

But they are plenty rare.
