Rust library to read and write AIFF and AIFF-C (AIFC) audio format.
Features:
- reading AIFF and AIFF-C
- writing AIFF and AIFF-C
- no heap memory allocations
- no unsafe code
- no panicking
- supports uncompressed integer and floating point samples
- supports compression types: μ-law, A-law and IMA ADPCM ("ima4")
- supports audio files up to 4 gigabytes
Out of scope:
- conversion between different sample formats (e.g., i16 to f32). There's so many ways to do the conversion that it's better that this crate doesn't do it.
Reading AIFF/AIFF-C file:
let mut stream = std::io::BufReader::new(std::fs::File::open("test.aiff").expect("Open failed"));
let mut reader = aifc::AifcReader::new(&mut stream).expect("Can't create reader");
let info = reader.read_info().expect("Can't read header");
for sample in reader.samples().expect("Can't iterate samples") {
println!("Got sample {:?}", sample.expect("Sample read error"));
}Writing AIFF-C file with the default 2 channels, 16 bits/sample and sample rate 44100:
let mut stream = std::io::BufWriter::new(std::fs::File::create("test.aiff").expect("Open failed"));
let info = aifc::AifcWriteInfo::default();
let mut writer = aifc::AifcWriter::new(&mut stream, &info).expect("Can't create writer");
writer.write_samples_i16(&[ 1, 2, 3, 4 ]).expect("Can't write samples");
writer.finalize().expect("Can't finalize");See the AIFC API documentation for details.
A simple AIFF player using aifc::AifcReader and tinyaudio:
cd examples/aifc-tinyaudio
cargo run filename.aiffToisto AIFF Test Suite is a submodule and needs to be fetched before running the tests.
cd aifc
git submodule update --init
./tools/test.shThe test should end with --- All tests OK..
Performance testing:
cargo benchThere is a GitHub Action called "Cross-platform tests" (cross-test.yml), which automatically
runs ./tools/test.sh for little-endian 64-bit x64_86 and big-endian 32-bit PowerPC.
