Is it possible to import Monkey's Audio in MKV/MKA?
Hi, I'm trying to import some .ape file in a MKV container because I wanted to use the Matroska chapters to make navigation points for this playlist, I'm using MKV Merge but it doesn't accept .ape files, do you know any other method? I'd rather avoid converting this file to some other format, if possible.

I know but when I open the .ape file using IsoBuster 3, it let's me extract the WAV files of each track, the problem is that these WAV files sound like random noise, even if I import these WAV files inside a MKV, it still sounds like random noise, so I thought that if MKV merge can import WAV file which was extracted from an .ape container, maybe there's some shortcut to import directly the whole .ape file, like making MKV merge believe that it's a MKA, sorry for the lame explanation, I've never tried something like this before (probably impossible, I guess).

Any quality loss is incurred during compression, not decompression. And of course the size is increased when you decompress. Don't you understand the difference between compressed and uncompressed audio? I would suggest you do some studies on fundamentals of audio and video compression.

I've just tried to compress a WAV using "Insane" compression and then decompress it again, the crc32 was the same before and after, in theory there was no quality loss during the compression phase nor the decompression, but while it was compressed the size was 60% reduced.

I will add, however, one thing that also appears to be confusing you. Compression always reduces the file size, that is what the word means. But you can have lossy or lossless compression. The former loses quality, the latter does not. Generally, lossy compression will give you a bigger file size reduction. I do not know the details of Monkey Audio to tell you if it is lossy or lossless, or can do both depending on the mode you select. You can research that yourself I'm sure. Good luck with your projects. |

Monkey's Audio is a lossless compression format. From http://wiki.hydrogenaudio.org/index....ess_comparison, it seems its compression is on par with FLAC, but is much slower to decode. Unless this article is out of date and Monkey's Audio has improved its compression, it doesnt appear to have any benefits over FLAC (slightly OT).
Unfortunately that is the extent of my knowledge about this format, especially since FLAC has much greater acceptance/compatilibity. |

Thanks everyone for the explanations, I'm just an amateour in video encoding and I didn't know that 100% lossless compressions existed for audio, I always thought that lossless were just codecs like lossy codecs but better for keeping the quality from raw files (at the cost of larger file size), now I understand that lossless are exactly like the raw files, but the difference is that they're not supported by many decoders, I'm using MPC-HC (from CCCP) to play compressed .ape without decompressing them (thanks to APE DirectShow Filter from CCCP probably), but since now I know how it works I'm going to recompress my .ape files in FLAC (which can be imported in mkv easily, just what I needed). So, thanks again and even though it's a bit late, merry xmas everyone and happy new year in advance!

You can always go to MKVToolNix mail list and request the feature, APe is open source right? if so, it should be trivial to implement.
and if you can't and they refuse for some reason, you could just convert it to flac, which is far easier to decode and is almost as efficient (something like 0.5% difference in comression between flac and ape) |
