Choose a tool for the result you need

EZAudio brings audio tasks into a web interface. The processing method depends on the tool: opening a tool in a browser does not mean all computation happens on your device. This overview describes current workflows; use each tool page for its available settings.

• Vocal Remover estimates vocals and accompaniment from a mixed song.
• Stem Splitter estimates four tracks: vocals, drums, bass and other instruments.
• Audio to Text transcribes speech. An optional summary is generated from the transcript.

Understand where processing happens

Audio Cutter, Audio Joiner, volume adjustment and reversal process audio on your device. Browser decoding support and memory affect the files you can edit.

Audio Converter, video audio extraction, compression, noise reduction and enhancement require an upload and use server audio processing. These utilities use no credits and have separate file and submission quotas. Noise reduction and enhancement use signal-processing presets; they do not reconstruct missing source detail.

Check limits before submitting

AI transcription and music separation use credits. Optional transcription summaries are charged separately. Guest transcription files are limited to 20 seconds regardless of balance. Read the billing rules and displayed task estimate; current plan details are on Pricing.

Review before reusing results

Listen to separated audio for bleed and distortion, check transcript names and numbers against the recording, and verify a summary's statements before sharing. Download a copy of results you want to keep. Read the Privacy Policy for uploaded file handling, and use recordings you have permission to process.
