What is this tool

AudioToolKit applies a light bass boost online for free, in your browser. A +6 dB low-shelf lift makes the low end clearly present on phone and laptop speakers without the muddiness of heavier settings. The boosted track downloads as MP3 or WAV, and the file is processed entirely on your device — no upload, no install, no account.
