What is crisp audio?
Crisp audio is speech with enough presence and air to be easy to understand. This tool lifts those upper frequencies so muffled voices sound clearer, and a warmth control puts low end back if the result turns thin. It shapes tone only and does not remove noise. It runs in your browser without uploading the file.
What does Crisp Audio do?
Crisp Audio makes muffled speech easier to understand by shaping its tone. It combines a high-pass filter, a presence peak and a little air in the top end. A warmth control adds a low shelf so the voice does not turn thin. Clarity runs from 0 to 100 percent and starts at 60 percent, and warmth runs from 0 to 100 percent and starts at 30 percent. It is an equalizer and not a noise remover, so it will not take out hiss. If the recording has steady hiss, use Noise Reduction first and then crisp. If the only problem is level, use Volume Booster instead. It is aimed at voice memos and call recordings, and it can add air to music. Very high clarity can sound harsh. It runs in your browser, so the file is not uploaded, and you can save a 16-bit WAV or an MP3. It is free, with no account and no watermark.

FAQ
Will this remove background noise?
No. Crisp Audio shapes tone and does not remove noise. It is an equalizer with a high-pass filter, a presence peak and a little air. For steady hiss, run Noise Reduction first and then crisp the cleaned file. Raising clarity on a noisy recording can make the hiss easier to hear.
Can it sound harsh?
Yes, if clarity is very high. A strong presence and air boost can make speech sound sharp or harsh. Lower the clarity amount or raise warmth, which adds a low shelf so the voice does not turn thin. Start near 60 percent clarity and 30 percent warmth, which are the defaults, and listen before you save.
Does it work on music?
It can add air to music, but it is aimed at speech, such as voice memos and call recordings. A full mix may sound thin or bright with these settings. For the low end of a song, use Bass Booster instead. Preview the result and keep the original file.
