AIFF and WAV hold the same kind of audio in two different wrappers, and Windows software and a lot of hardware only read one of them. Filemorph rewraps an AIFF as a 16-bit WAV on your iPhone, with no encoding step and no upload.
AIFF is Apple's uncompressed audio format, common in Logic Pro and GarageBand exports and in older Mac sample libraries. WAV is the equivalent on Windows and in most hardware: samplers, field recorders, car systems and game engines. Both store raw PCM samples; the technical difference is byte order, AIFF big-endian and WAV little-endian, plus the header that describes the audio.
Filemorph reads the AIFF with Apple's AVFoundation and writes a 16-bit WAV at the same sample rate and channel count. Because neither format compresses audio, no encoding happens, and a 16-bit source comes through sample for sample. The file size stays about the same, since the samples are the same and only the container changes.
In the app: Transcode (Output Format: WAV).
Reach. WAV is read by essentially every audio program and device on every platform, while AIFF support outside Apple software is patchy. A WAV copy of a GarageBand or Logic export travels to a collaborator on Windows, a hardware sampler or a video editor without a format complaint, and it costs nothing in sound quality for 16-bit audio.
Yes. Unlike web converters that upload your files to a server, Filemorph converts every file locally using Apple's frameworks. Nothing leaves your device, and it works with no internet connection. This operation is part of Filemorph Pro ($29.99/year, 7-day free trial on monthly and annual plans).
For a 16-bit AIFF, yes. Both formats store uncompressed PCM, so the samples are copied over and only the container and byte order change. Filemorph writes 16-bit WAV, so a 24-bit AIFF is reduced to 16-bit on the way; keep the original if you are still mixing at the higher depth.
No, about the same. Neither format compresses audio, so a file of the same length, sample rate and bit depth is nearly identical in size. If you want a smaller file, convert to M4A or MP3 instead.
No, audio Transcode is part of Filemorph Pro ($29.99 a year, 7-day free trial on monthly and annual plans).
On-device, no upload. Plus 300+ more file operations.
