Comment on Apple Lossless decoder with 24-bit support. by Mervin Beng

Thanks for the software! It was invaluable for my logitech media server setup.

There was a problem with 24/96 ALAC files — they were decoded as sample rate 30464Hz (0×7700) instead of 96000 (0×17700). I’ve created a kludged version that corrects this. On demux.c:

/* sample rate – 32bit fixed point = 16bit?? */
qtmovie->res->sample_rate = stream_read_uint16(qtmovie->stream);
if(qtmovie->res->sample_rate == 30464) /* 96000 – 65536 */
qtmovie->res->sample_rate += 65536; /* KLUDGE!! */
if(qtmovie->res->sample_rate == 22664) /* 88200 – 65536 */
qtmovie->res->sample_rate += 65536; /* KLUDGE!! */
if(qtmovie->res->sample_rate == 60928) /* 192000 – 2*65536 */
qtmovie->res->sample_rate += (2*65536); /* KLUDGE!! */
if(qtmovie->res->sample_rate == 45328) /* 176400 – 2*65536 */
qtmovie->res->sample_rate += (2*65536); /* KLUDGE!! */
entry_remaining -= 2;

It seems to work with the 24/96 materials I have.

Anyone compiling alac for use with hi-res files, please try this and post your results.

This is a very interesting solution. Is this something that could also work with WPF Windows? Has anyone published a solution for WPF?

Interesting article. As of .NET 4 it looks like RegistryKey no longer hides the Dispose method.

Interface hiding also explains why the expansion of a using statement’s finally block expands to:

if (resource != null) ((IDisposable)resource).Dispose();

If the resource was not cast to an IDisposable then, if the interface was hidden (implemented explicitly), it would not be possible to call Dispose on the resource object without the cast.

That’s an amazing solution. I second your statement about being as elegant as it can get.

Works like a charm.

Thanks heaps for that.

Error 2 The type or namespace name ‘Form’ could not be found (are you missing a using directive or an assembly reference?)

FYI the copyright date printed when running the 9/5/2009 version (from http://craz.net/programs/itunes/files/alac_decoder-0.2.0.tgz) still shows as 2005. Since the version is not embedded in the software, it is hard to tell which version one is looking at except from the name of the .tgz archive file.

You might want to embed the version number (e.g. 0.2.0) and include it in the help message, so people can tell what version of a binary they are running.

Thanks for a great piece of software!
