AIFF is the native uncompressed format on the Mac side of audio work, and some sample libraries, older Mac tools and hardware expect it. Filemorph rewraps a WAV as AIFF on your iPhone, no upload involved.
WAV and AIFF are the two uncompressed audio containers most people meet: WAV from Windows, recorders and the web, AIFF from Apple software and Mac-centric sample libraries. They hold the same PCM samples in a different byte order with a different header. Most modern software reads both, but some tools still expect one specifically, and a library or project that is all AIFF is easier to manage when every file matches.
Filemorph reads the WAV with Apple's AVFoundation and writes a 16-bit AIFF at the same sample rate and channel count. No compression is involved, so the audio in a 16-bit WAV comes through unchanged. The file stays about the same size, since the samples are identical and only the wrapper is different.
In the app: Transcode (Output Format: AIFF).
Consistency with a Mac-based workflow. Some sample libraries, older Mac applications and hardware expect AIFF specifically, and a project where every file shares one format is simpler to move, back up and hand off. Because both formats are uncompressed, the switch 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 WAV, yes. Both are uncompressed PCM formats, so the samples are copied and only the container changes. Filemorph writes 16-bit AIFF, so a 24-bit or 32-bit float WAV is reduced to 16-bit; keep the original if you are still mixing at a higher depth.
Many Windows audio programs open AIFF, but support is less universal than for WAV. If the file is headed to a Windows user or a piece of hardware, WAV is usually the safer choice; convert to AIFF when the destination is Mac software or a library that asks for it.
No, audio Transcode is part of Filemorph Pro ($29.99 a year, 7-day free trial on monthly and annual plans).
