The SoundStretch utility is documented separately with copyright years from 2002 through 2024. The change history shows long-running maintenance across build systems and platforms: GNU autotools support, CMake support, Android support, OpenMP acceleration from the 1.9 series, SIMD and autovectorization work, and library/API fixes through the 2.x series. ### Adoption history SoundTouch became the kind of low-level multimedia component that distribution packagers expose both as a library and as a small CLI utility. In this input it is present through Homebrew as `sound-touch` and through Debian/Ubuntu as `soundstretch`. ### How it is used Developers embed the library for tempo, pitch, rate, BPM, and time-stretch processing. Command-line users use `soundstretch infilename outfilename [switches]` for WAV audio, including tempo changes, pitch changes, playback-rate changes, BPM detection, and stdout piping. ### Why package nerds care Package nerds care about SoundTouch because it is both a classic Unix-style media library and a testable CLI. It exposes real audio-DSP behavior while still building with familiar portable toolchains such as autotools and CMake. ### Timeline - 2001: SoundTouch library copyright period begins in the official README. - 2002: SoundStretch utility copyright period begins in the official README. - 1.1.1: Library moved under the LGPL according to the official change history. - 1.9: OpenMP parallel computation support added according to the official README. - 2021: Official Codeberg repository created. - 2025: Official README documents SoundTouch 2.4.x-era maintenance. ### Related projects - SoundStretch is the command-line utility distributed with SoundTouch. - The SoundTouch BPM library and SoundTouchDLL interface are documented in the official README. ### Sources - - ## Security Notes broad file, network, media, or database tool signal. - **Geiger risk:** blue / medium - broad file, network, media, or database tool signal ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** sound-touch - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Other Package-Manager Records - Debian apt - soundstretch - 2.4.0+ds-1: installed executable or alias match | Debian stable package indexes: soundstretch from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | Stretches and pitch-shifts sound independently | https://www.surina.net/soundtouch/ - Ubuntu apt - soundstretch - 2.3.2+ds1-1build1: installed executable or alias match | Ubuntu 24.04 LTS package indexes: soundstretch from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | Stretches and pitch-shifts sound independently | https://www.surina.net/soundtouch/ ## Related links - [Secret-risk packages](https://www.automicvault.com/pkg/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Media and graphics packages](https://www.automicvault.com/pkg/media-graphics-tools/) - Matched media, image, audio, video, or graphics metadata. - [autoconf](https://www.automicvault.com/pkg/brew/autoconf/) - Build dependency declared by Homebrew. - [automake](https://www.automicvault.com/pkg/brew/automake/) - Build dependency declared by Homebrew. - [libtool](https://www.automicvault.com/pkg/brew/libtool/) - Build dependency declared by Homebrew. - [rubberband](https://www.automicvault.com/pkg/brew/rubberband/) - Shares av.db curated category or tags: audio, cli, library, media, pitch-shifting. - [vorbisgain](https://www.automicvault.com/pkg/brew/vorbisgain/) - Shares av.db curated category or tags: audio, audio-processing, cli, media. - [adplug](https://www.automicvault.com/pkg/brew/adplug/) - Shares av.db curated category or tags: audio, cli, library, media. - [alsa-lib](https://www.automicvault.com/pkg/brew/alsa-lib/) - Shares av.db curated category or tags: audio, cli, library, media. - [chromaprint](https://www.automicvault.com/pkg/brew/chromaprint/) - Shares av.db curated category or tags: audio, cli, library, media. - [ecasound](https://www.automicvault.com/pkg/brew/ecasound/) - Shares av.db curated category or tags: audio, audio-processing, cli, media. - [fluid-synth](https://www.automicvault.com/pkg/brew/fluid-synth/) - Shares av.db curated category or tags: audio, cli, library, media. - [freealut](https://www.automicvault.com/pkg/brew/freealut/) - Shares av.db curated category or tags: audio, cli, library, media. - [sox_ng](https://www.automicvault.com/pkg/brew/sox-ng/) - Both packages work with overlapping file formats or content types.
