🔊 💻 👁️Audio content visualization tool

Demo

Audeye is a terminal tool to visualize audio content, written in Rust

• wav / aif / flac / ogg-vorbis and many more (see : libsndfile format compatibility v1.0.31)
• mono / stereo / 5.1 / 7.1 ... (up to 9 channels)
• Waveform peak & RMS visualizer
• Spectrogram visualizer
• Signal normalization
• Zoom and move inside both visualizers
• Metadata display

• space : display bindings
• left arrow / right arrow : navigate through panels
• j / k : zoom out / in
• h / l : move left / right
• [0-9] : activate / deactivate display of the corresponding channel
• Esc : reset channel layout

• -n : normalize the audio signal before displaying it (not channel aware)
• --fft-window-size
• --fft-window-type : hanning / hamming / blackman / uniform
• --fft-overlap
• --fft-db-threshold : minimum energy level to consider (in dB)
• --fft-padding-type : zeros / loop / ramp

The padding type determine how to fill the sides of each FFT window when at the very edges of the audio content

• Zeros : fill with zeros
• Ramp : fill with zeros and a small amplitude ramp to match the last/next sample
• Loop : fill with the end/beginning of the audio file

Audeye rely on Rust bindings to libsndfile

apt-get install libsndfile1-dev

cargo install audeye

1. Install Rust
2. Install libsndfile
3. Then run cargo run <AUDIO_FILE_PATH>

Please consider audeye is still in early development, feedbacks are very welcome

• cargo
• libsndfile
• precommit
• clippy
• rustfmt
