MC 18.0.187 now allows the full use of DSP Studio when performing audio (or audio extraction from video (http://yabb.jriver.com/interact/index.php?topic=80684.0)).
This makes it possible to convert audio to different sample rates, make a stereo track from a 5.1 file (or the reverse), apply Replay Gain to a set of files you're converting, etc.
A few additional notes:
- DSD now works nicely with conversion (in the standalone tool or for a handheld)
- Files that are over 24-bit will be converted to 24-bit (with dither) by the converter. This is because most encoders don't support input greater than 24-bit.
- A side effect of this change is that DSP Studio settings for Handheld also honor the sample rate and channel mixing options from 'Output Format'. These were previously ignored.
- This has been a long-standing request. I think I've said "I agree, we should do that" once a month for several years :P
-
This is great, thanks. Being able to convert DSD files, or apply DSP to files I'm sending to portable devices is especially useful. (now everything can have crossfeed/hrtf!)
-
Great News :)
-
This is great, thanks!!
Converted dff and applied DSP settings succesfully.
One question though, now that bit depth is removed from DSP, if I wanted to change bit depth, can I do that? Dff is automatically changed to 24 bit flac, but what if I wanted it to be 16?

It's not currently possible.
We could add it as a converter option if there's enough demand.

When converting DSD to ALAC, it's being converted to a 24-bit file, which is fine for me.
But I suspect there are a number of portable devices out there which only support 16-bit audio, so the option might be useful. (this is not a request from me though)
P.S. now that I can convert DSD files easily, I've come across a few interesting things…
Looks like they just converted the 44.1 CD master to DSD (http://www.abload.de/img/bowiekuqhf.png)
That should probably be filtered out… (http://www.abload.de/img/beckcxr5o.png)
In fact, everything I have seen so far, seems to suggest that you shouldn't use anything other than the "Safe (24kHz at 48dB/octave)" filter for DSD playback.
It's the only one which actually filters out all the ultrasonic noise, and I've yet to see anything which appears to have audio content above that. (though it's difficult to classify anything above 20kHz as "audio" content)

of bit depth conversion...

This would be useful - for converting hi-rez for the car, for example. Worth doing, IMHO.

I'm not sure if I understand, but MP3 has been one of the possible encoding formats (basically) forever.
When you convert, there's a combobox that you can open and select from a variety of popular audio formats.

I tried to convert a song to MP3 and it didn't work.
Source: SACD
Converting the same song to flac worked just fine.

You'll have to enable resampling with DSP Studio since the MP3 format doesn't support 352.8kHz, which is what SACD outputs as PCM by default.
-
Sorry, forgot to add.....
Resample setting for MP3 was 44100khz and it didn't work.....
Would be nice if Standard settings for MP3 conversions were 44100khz and 16Bit without changing DSP settings, because many portable players don't work with other settings.
-
Just converted a few SACD ISO tracks to various formats including mp3's at both 48 and 44.1 without any difficulties. So it's obviously possible. Maybe you could post a snapshot of both mp3 conversion settings and DSP settings to see if any of us can spot an error.
One weird thing however, is that converting SACD ISO to FLAC 2.1 channels creates a file that has still 6 channels. Not sure if this is to be expected or not.

2.1 uses a 6 channel (5.1) container. This is because basically no audio hardware supports 2.1.
I suppose the encoder could be smarter, although the empty channels are basically free with lossless compression.
-
I had a feeling that was the case. Thanks for clarifying.

@Claude Lapalme
Shouldn't be too difficult.What settings do you use to convert sacd to mp3.
I played around with DSP settings, but none of them worked.....
It tries to start and after a few seconds it says: finished, but nothings converted.
System: Windows 7 or 8?
-
Here are the two settings screens. It's true that I used CBR/ABR encoding. Did not test VBR
-
Works fine with VBR too. Just tested
-
Try Faster CBR Encoding.Your setting works.
But i tried to use standard CBR Encoding, because my car radio has some troubles with vbr/abr bitrates.
I don't know why cbr isn't working.
-
Indeed, faster CBR doesn't work for me either.
-
You'll have to forgive me as I'm new to this, so what your saying is I can take the audio from a DTS-HD 5.1 BD and download it to the MC and play back in down-mixed stereo? That would be worth it alone!
