Audio Tools

Audio is unforgiving: a noisy recording cannot be unheard, and a podcast without a transcript loses half its audience. The eight tools here cover the recording lifecycle — cleanup, transcription, analysis, and format housekeeping — with the heavy jobs running server-side and the quick ones in your browser.

Cleanup and production: Audio Denoise removes hiss, hum, and background noise from voice recordings — the first tool to reach for with field recordings or laptop-microphone calls. Vocal Separator splits a track into vocals and instrumental, which is how you make karaoke versions, isolate an instrument, or pull a sample. Audio Merge joins takes into one file, and Cloud Audio Studio handles heavier conversions and effects server-side.

Understanding and metadata: Audio to Text transcribes speech to written text — interviews, lectures, meeting notes — and works best with one clear speaker. Audio BPM detects tempo, useful for DJs building sets, video editors matching cuts to beats, and fitness instructors pacing playlists. Audio Meta reads and fixes the tags (title, artist, artwork) that music players rely on. Text to Speech reads written text aloud in natural voices for narration drafts and accessibility checks.

How to choose: denoise before you transcribe — clean audio measurably improves transcription accuracy. If a track sounds muddy, try vocal separation first to hear what is actually in the mix. For metadata, fix tags before merging files so the final file inherits correct information.

Practical tips: record in the quietest room you can find; denoise works better on light noise than on heavy noise. Keep lossless masters and export compressed copies for distribution. Cloud jobs show their credit cost up front and failed jobs refund automatically.
