Generate beautiful waveform visualizations from audio files. Choose from bars, mirror, line, or circular styles. Customize colors and export as PNG.
Generate pure audio tones with sine, square, sawtooth, and triangle waveforms. Create multiple oscillators, binaural beats, and export as WAV.
Detect the tempo (BPM) of any audio file. Includes tap tempo feature and genre reference guide.
Need an MP3 but only have a WAV? Converting between audio formats is straightforward here. Pick your source file, choose the target format, adjust bitrate or quality if you want, and convert. The tool handles MP3, WAV, OGG, AAC, M4A, and FLAC. Everything runs in-browser — no file uploads, no accounts.
Lossy formats like MP3, AAC, and OGG achieve small file sizes by discarding audio data that is difficult for human hearing to detect. Higher bitrates preserve more detail; 192 kbps is a solid middle ground, while 320 kbps is effectively transparent for most listeners. Lossless formats like FLAC and WAV keep every sample intact at the cost of larger files. When converting from lossy to lossless, the missing data is not recovered — the file simply gets bigger without gaining quality. Converting from lossless to lossy is the standard practice for producing distribution-ready files.
Convert files to a format your player, phone, or car stereo actually supports.
Turn large WAV recordings into compact MP3s for email or cloud storage.
Convert lossy files to FLAC or WAV when you want a lossless master copy of new recordings.
No. Once audio data has been discarded by lossy compression, converting to a lossless format cannot restore it.
For music, 192-256 kbps offers a good quality-to-size balance. For speech, 128 kbps is usually sufficient.
