iff2aiff is a command-line tool for converting IFF (Interchange File Format)
sound files to Apple AIFF (Audio IFF) or AIFC with uncompressed PCM. It is part
of the ifftools package for amigazen project ToolKit.
Features:
- Reads common IFF audio forms: 8SVX, 16SV, AIFF, AIFC, MAUD
- Writes standard FORM AIFF or FORM AIFC with PCM sample data
- Preserves sample rate, channel count, and duration from the source
- Output 8-bit or 16-bit according to decoded source (otherwise 16-bit path)
- Optional AIFC container (AIFC or COMPRESS switch)
- FORCE and QUIET for scripting
Version History
- 1.0: First public release (IFFSound.lib integration, AIFF/AIFC writer)
Requirements:
- AmigaOS 3.1 or higher
- 68020 CPU recommended (source available to build other targets)
Usage:
iff2aiff SOURCE TARGET [OPTIONS]
Arguments:
SOURCE - Input IFF audio file (required)
TARGET - Output AIFF or AIFC file (required)
Options:
FORCE - Overwrite existing output file without prompting
QUIET - Suppress normal output messages (errors still shown)
AIFC or COMPRESS - Write AIFC (FORM AIFC) instead of classic AIFF
Examples:
iff2aiff sample.8svx ram:sample.aiff
iff2aiff music.maud ram:music.aiff FORCE
iff2aiff clip.aiff ram:out.aifc AIFC
iff2aiff voice.iff ram:out.aiff QUIET
N.B. file extension is not used to recognize file types
Supported IFF sound inputs (typical):
- 8SVX - 8-bit sampled voice
- 16SV - 16-bit sampled voice
- AIFF / AIFC - re-wrapped to chosen output container
- MAUD - Amiga musical data (when supported by decoder)
Non-quiet output lists source FORM, rate/channels/bit depth, target profile,
frame count, PCM size, and written file size.
