Audio tools help with recordings, music clips and voice notes. Format conversion is the most common job. MP3 Converter gives you the most widely supported file, WAV Converter produces uncompressed audio, FLAC Converter is lossless, and the AAC Converter covers the AAC format. If file size matters most, choose a compressed format. If you plan to edit further, an uncompressed or lossless one keeps more detail.
Editing tools handle the rest. Audio Cutter trims a file to a start time and duration, Merge Audio joins tracks, and Volume Booster raises or lowers loudness. The Noise Reducer reduces background hiss, and the Audio Speed Changer speeds up or slows down audio without changing its pitch. The Voice Recorder records from your microphone, and your browser will ask for permission first.
Files are processed in your browser and are not uploaded to a server. Audio tools may download a processing engine the first time you use them, so the first run can take a moment. Noise reduction improves a recording but cannot fully repair a very poor one. Large files take longer to process, so trim or cut first if you only need part of a recording.
