BTR AMP
Supported audio formats
BTR AMP plays virtually any audio format — lossless, lossy, and hi-res up to 96kHz/24-bit and beyond, including DSD up to DSD256 — in one library, with the exact codec shown on every track. Each format below has its own page covering how playback works on iOS and how to get your files onto the device. See all features for everything else the player does.
Hi-res
Beyond CD quality — for USB DACs and high-rate masters.
Lossless
Bit-perfect reproductions of the original audio.
FLAC
The most common lossless format — played natively, hi-res included.
ALAC
Apple Lossless — in the same library as your FLAC, not a separate app.
AIFF
Uncompressed PCM with proper tagging — played at full resolution.
APE
High-compression lossless rips — played directly, no FLAC conversion.
WavPack
The open lossless workhorse — .wv files play natively.
TTA
Free lossless from the archiving world — .tta plays as-is.
Lossy
Compact formats — played as encoded, never re-converted.
MP3
The universal format — organized properly at 50,000+ songs.
OGG Vorbis & Opus
The open lossy codecs iOS never adopted — played without conversion.
Musepack
The audiophile lossy codec of the 2000s — still playable, untouched.
AAC
The iTunes-era standard — with organization the Music app doesn't offer.
M4A
The MP4 audio family — M4A, M4B audiobooks, and MP4 audio in one player.
BTR AMP also imports M3U playlist files, so playlists built elsewhere carry over with your music.
