Phone voice memos, Zoom recordings, and older podcast tracks frequently suffer from low recording gain and microphone distance. Traditional audio software like Audacity requires complex installations and steep learning curves. BuzzyTools uses native WebAudio API gain filters to boost amplitude cleanly up to 200%, processing every sample in your browser memory with zero server uploads.
Boost quiet audio recorded from distant speakers in conference rooms or outdoor settings.
Amplify faint professor microphones to hear every word clearly during study sessions.
Level up low-volume audio tracks so you can listen comfortably in noisy environments or cars.
Match voiceover loudness with background music tracks before importing to video editing software.
Our engine uses linear gain curves designed to maximize volume while minimizing digital clipping. For best results, increase volume incrementally until dialogue is crisp.
We support all major audio formats including MP3, WAV, AAC, M4A, FLAC, and OGG.
Files up to 75MB and 6 minutes in duration are processed with maximum speed directly in browser memory.
