  • [Audio] The MQA Controversy: How an inferior format tried to take over the high-end audio market and caused major backlash
    1 project | /r/HobbyDrama | 9 Nov 2022
    Excessive licensing costs weren’t the only concern surrounding MQA though. MQA is touted as being DRM free, with audio streams able to be stored in the very popular, open source FLAC format. Only the lower resolution 16-bit audio is truly DRM free however. MQA’s authentication watermarking must be present in the file, and properly validated at playback, otherwise MQA decoders will refuse to unfold the audio to it’s full resolution. In this way, MQA acts as a sort of “soft-DRM”, that prevents recordings form being played at their maximum quality without both permission from the rights holder, and validation from MQA Ltd. All the issues surrounding MQA’s licensing and copy protection are explored in more detail in this article from 2017.

  • iPod classic and flac??
    1 project | /r/ipod | 10 Mar 2023
    Second, you will want to install the foobar encoder pack and set up qaac (here's the qaac wiki). In short, apple's AAC/ALAC encoder in iTunes is the best around (better than Nero, Fraunhoefer, ffmpeg, etc) and ensures full compatibility with iPods. But fuck iTunes, you know, for being difficult. So qaac takes the encoder binaries from your installation of iTunes and sets it up as a standalone program which you can use however and wherever you want. So you set up qaac and then tell foobar to use qaac to do all your AAC/ALAC encodings and you get the benefits of apple's encoder without the nonsense of iTunes being uncooperative.
  • Is there a way to make an ipod classic support music beyond 48khz and 24 bits?
    1 project | /r/ipod | 3 Feb 2023
    I use qaac as a CLI wrapper for the iTunes encoder. I don't use foobar, but I'm sure there's the option to set up using an external encoder. Every music manager I've ever used (except iTunes of course) has some way of setting up an external encoder via a command line.

    I'm running an ABX test right now between that and a transcode made using qAAC, which is a windows port of Apple's AAC codec. Here is the spectogram of that, as proof.
  • AAC 320k is the best "lossy" compromise to FLAC
    1 project | /r/audiophile | 24 Jan 2023
    AAC is still my go-to lossy codec for mobile purposes, although 256kbps is enough for me. it's also worth poiinting out that not all encoders are created equal - Apple's own encoder far superior to FAAC, for example, so Windows or Linux users outside the Apple ecosystem should use qaac instead, as it is a port.

  • For our ipods, what software you guys use?
    2 projects | /r/ipod | 11 Nov 2022
    Qaac is the best AAC/ALAC solution as it uses apple's own libraries that are included with iTunes. iPods sometimes don't like files that were made with other encoders, so using apple's own libraries ensures the files will play. Setting it up might look intimidating if you aren't familiar with command line input though. Once set up, you can configure Media Monkey, EAC, etc to use qaac as an external encoder.

  • iTunes Alternatives? Foobar2000 does not seem to work anymore

    In any case, you'll need to provide the ALAC encoder since it isn't included with either MM or MB, and I'm pretty sure it's the same with the others on that list. Setting up qaac as an external encoder isn't hard, though you do need to follow instructions.
