Audioalter is a free, browser-based collection of audio tools. Its homepage describes it as an online audio toolkit, a collection of easy-to-use web tools for all your audio files. It lists effects such as 3D audio, an auto panner and a bass booster, and AlternativeTo says you can change speed, volume, pitch and duration.

Directory pages also mention a vocal remover, trimmer, format converter, extraction of audio from video, BPM detection, spectrograms, an equalizer and reverb or spatial audio. Because it runs in the browser, there is nothing to install, and review sites describe it as aimed at beginners, podcasters, musicians and video creators. Several directories label it as AI, but the tools read as conventional audio processing, so treat the label cautiously.

Directories list it as free to use, and none of the sources found showed a paid plan. It depends on a stable internet connection. Only process audio you own or have permission to change, and be careful with the vocal remover on copyrighted songs. Results from quick online tools can be lower quality than a desktop editor.
