Remove electrical hum (50/60Hz and harmonics) from audio
Call this tool from your code in three languages.
# 1) Upload each file first → returns { filePath }
curl -X POST 'https://api.elysiatools.com/upload/audio-hum-removal' \
-F 'file=@/path/to/audioFile.ext'
# 2) Call the tool with the returned filePath values
curl -X POST 'https://api.elysiatools.com/en/api/tools/audio-hum-removal' \
-F 'audioFile=/path/to/file.ext' \
-F 'preset=60hz' \
-F 'customFrequency=60' \
-F 'includeHarmonics=true' \
-F 'widthHz=3' \
-F 'depthDb=-30' \
-F 'outputFormat=mp3'Send a POST request with your inputs as JSON. File parameters require a separate upload first.

}| Width of frequency cut. Lower (1-5Hz) is better for preserving audio. |
| depthDb | number | No | How much to reduce the target frequencies. More negative = stronger reduction. |
