TarsosDSP is a pure-Java framework for real-time audio processing and music information retrieval, with no external dependencies. It implements pitch detection algorithms (YIN, McLeod, dynamic wavelet), onset detection, DTMF decoding, time stretching, resampling, filters, synthesis, and audio effects.

Use cases

• detect pitch of a microphone input in real time in Java
• detect percussion onsets in an audio stream
• decode DTMF tones from audio
• time-stretch or pitch-shift audio without changing the other
• apply audio effects and filters to a live audio signal
• build a tuner or transcription tool in Java
• teach or prototype DSP algorithms with readable Java code

When to choose

• you need real-time audio analysis or effects in pure Java with zero external dependencies
• you want well-documented, readable implementations of classic pitch detection and onset detection algorithms
• you are doing music information retrieval research or teaching DSP in Java
• you need a JVM library that also runs on Android

When to avoid

• you need production-grade, low-latency audio in a non-JVM language
• you require GPU-accelerated or deep-learning-based audio models
• you need a full DAW-style audio editing application rather than a processing library
• GPL-3.0 licensing is incompatible with your project
