Monkey's Audio (APE) achieves some of the highest lossless compression ratios available — typically 55-65% of the original PCM size — but its decoder is slow and platform support is extremely limited. AAC (Advanced Audio Coding) is the modern lossy standard used by Apple Music, YouTube, Spotify (for some content), and virtually every mobile device and browser. Converting APE to AAC makes your lossless music collection playable everywhere while maintaining excellent audio quality at compact file sizes.
APE has almost no native playback support outside of foobar2000, Winamp, and a few Asian media players. You cannot play APE on an iPhone, in a web browser, or on most car stereos. AAC solves all of these problems — it is the default audio codec on Apple devices, natively supported on Android, and playable in every modern browser. At 256 kbps, AAC is perceptually transparent to most listeners, meaning the quality difference from lossless APE is inaudible to the majority of people in normal listening conditions.
FFmpeg decodes the APE file to 16-bit/44.1 kHz PCM (CD quality), then encodes it using the AAC-LC codec at a configurable bit rate (128-320 kbps). The default 256 kbps setting is considered perceptually transparent for most music. The encoder processes the full stereo signal with psychoacoustic modeling to allocate bits efficiently across frequency bands.
At 256 kbps, AAC-LC is indistinguishable from the lossless APE source in double-blind listening tests for the vast majority of listeners. At 128 kbps, subtle differences may be perceptible on complex musical passages with high-quality headphones. The APE source ensures the AAC encoder receives a pristine input with no pre-existing lossy artifacts.
