WavPack is an open lossless codec with a long history in the archiving community — efficient compression, robust error handling, and .wv files that many careful rippers standardized on.
Why iPhone can't play WavPack natively
iOS has no WavPack support — the Music app cannot open a .wv file, and Files-app previews do not apply. As with APE, the conventional answer has been converting the collection to FLAC or ALAC before it can reach an iPhone, forking the library in the process.
How BTR AMP plays WavPack
BTR AMP plays WavPack directly — added in version 15.0 alongside APE, Musepack, TTA, and the OGG codecs. Files play losslessly at their original quality with the exact codec shown per track, and the on-device metadata editor covers APE tags, the tag system WavPack files use. Your .wv rips share one library with FLAC, AIFF, and every other supported format, kept navigable by custom tabs and smart playlists at any scale.
Getting your WavPack files onto your iPhone
WavPack files transfer the same as the rest of your library.
Send files over Wi-Fi from any browser on your computer (Connect → Wi-Fi Transfer), pull them from Google Drive, OneDrive, iCloud Drive, an SMB share, or WebDAV, use AirDrop, or play straight from a USB drive. The transfer guide walks through each method, and the importing guide covers the details.
