ADTS Tool

ADTS Tool is a command line tool for lossless cutting of ADTS files. ADTS files typically contain AAC audio and often have an extension of .aac.

Lossless cutting works by cutting files on ADTS frame boundaries. A frame contains 1024 samples, which means an input with a sample rate of 44.1 kHz can only be cut to an accuracy of ~23 ms.

ADTS Tool requires Java 8 to build and run.

Building

Clone the repo and build using the Gradle wrapper:

$ git clone https://github.com/bencampion/adts-tool.git
$ ./gradlew clean build

This will produce zip and tar archives in build/distributions that contain all dependencies along with start scripts for Bash and Windows.
