[Apple] Apple Releases ALAC as Open Source

post #1 of 30

http://alac.macosforge.org/post/welc...codec-project/

Apple recently released their Apple Lossless Audio Codec as an open source project under the Apache license, while I'm a huge fan of the FLAC codec myself I see this as a positive move in the right direction for Apple however meaningless the gesture is to me. Any thoughts on this vs FLAC?

Quote:
The Apple Lossless Audio Codec (ALAC) is an audio codec developed by Apple and supported on iPhone, iPad, most iPods, Mac and iTunes. ALAC is a data compression method which reduces the size of audio files with no loss of information. A decoded ALAC stream is bit-for-bit identical to the original uncompressed audio file.

The more open codecs the better.

Honestly cannot tell the difference between FLAC and ALAC. most of my music is FLAC source encoded to ALAC.

Although there's always someone who CAN tell the difference between ALAC and FLAC.

So could I use this on my MP3s to make them sound better? It mentioned a converter, though I didn't understand much of it.

No. You need to rip from a quality source (e.g. CD or something) for it to retain quality. If you transcode your 128kbps MP3 file to FLAC/ALAC/whatever, it's still going to be essentially a 128kbps MP3 file, albeit larger file size.

They're lossless.... there's really no difference that can be perceived because the end-quality after decoding should be perfect.
I think FLAC is more efficient (filesize-wise) though.

No one can. The output is identical... the compression percentage (dependent on patterns), encoding/decoding resources, and adoption rate are the differences.
Once again...

This^ I've found smaller file sizes using FLAC than I have with ALAC and on top of that in my experience Android devices have better support for FLAC (CyanogenMod ones anyways). Although like I said I see this as a step in the right direction especially since iOS devices only like Apple formats XD

Read a thread a while-back on how all lossless audio codecs sound identical but some have better compression and some are easier to rip and some are easier to listen to(less resources) which can make a significant difference in portable devices.

FLAC is the middle ground I believe. ALAC will probably just be more easier to play on Apple devices though(albeit larger). Completely made that last part up though... Just a shot in the dark really.
