Test if qaac is correctly installed and added to your PATH by opening the command prompt (cmd.exe) and typingĬode: qaac 2.xx, CoreAudioToolbox 7.xx.x.x Quote: Note: If you haven't already, it's a good idea to add eac3to to your PATH as well by clicking Edit. This will enable qaac to use Apple's official library to encode AAC files.Īfter extracting qaac it is a good idea to add it to your system PATH so it can be called from any directory.

> Apple Application Support x86 (updated: Feb 2017) (You can also extract it from the iTunes Installer yourself using 7-zip.) This makes qaac especially desirable for encoding commentary tracks. Qaac uses Apple's implementation of the AAC encoder, which is currently considered to be superior to Nero's AAC encoder at low bitrates. Instead of choosing a fixed bitrate we set quality and delivers the most compressed and better quality track than eac3to or other encoders. *Incase if source is LPCM/PCM do convert them to DTS-HD MA.ĪAC is an advanced lossy audio codec, which is well-suited for encoding 2.0 audio, achieving transparency at around 180 kbps.įor Mono/Stereo Audio encodes Qaac is vastly used and delivers the most proper size/quality ratio among all. | Commentary&| => 320 || AAC/Opus | AAC/Opus | AAC/Opus | AAC/Opus | | Lossy | Any || Leave | Leave | Leave | Leave | | Lossless | 1.0/2.0 || FLAC | FLAC/AAC | FLAC/AAC | AAC | | Source | Channels || Encode Resolution | Surround Audio (2.1 and above) : AC3 / DTS (Core) / E-AC3 Mono/Stereo Audio (1.0/2.0) : AAC / FLAC (For HD Only) Here's a chart of audio that is used with encodes below : There are varieties of options you can choose but this guide will be mostly for newcomers who are learning and this is what is considered proper in the P2P world. You should only encode from lossless sources.Įncodes with eac3to suffers from clipping in multiple timestraps also significantly worsens surround channels.įirstly, Audio channels are the most important factor which is to be considered first. Re-encoding only significantly worsens quality. WARNING: Do not re-encode an already-compressed audio/Lossy Audio like AAC/AC3/DTS/DTS-HR/E-AC3.
