dtmf

A no-std DTMF decoder for Rust. Can be used on a microcontroller or on a normal PC.

Usage

```rust // Load in our audio samples // This can also be done in real time from the sound card let mut samplefile = File::open("data/dtmftest.wav").unwrap(); let (header, data) = wav::read(&mut samplefile).unwrap(); let data = data.tryinto_sixteen().unwrap();

// set up our decoder let mut decoder = Decoder::new(header.sampling_rate, |tone, state| { println!("{:?}: {:?}", tone, state); });

// can process all samples at once, or in smaller batches decoder.process(&data); ```
