Tool usage guide
The Audio Band-Reject Filter removes a specific band of frequencies from audio files. It targets a narrow range around a center frequency to reduce unwanted sounds like hum, resonance, or harshness, enhancing audio clarity.
Background
A podcast episode has a persistent 60 Hz hum from electrical interference in the recording environment.
Problem
The hum reduces audio quality and makes the content sound unprofessional.
How to use
Upload the audio file, set center frequency to 60 Hz, bandwidth to 50 Hz, and output format to MP3.
Outcome
The hum is significantly reduced, resulting in cleaner and more professional audio.
Background
During a live concert recording, a feedback tone at 2 kHz disrupts the audio feed.
Problem
Feedback causes distortion and needs to be removed without affecting other frequencies.
How to use
Process the audio by setting center frequency to 2000 Hz and bandwidth to 100 Hz to narrowly target the feedback.
Outcome
The feedback is eliminated, preserving the clarity and quality of the live performance.
The tool accepts common audio formats like MP3, WAV, AAC, and others listed in the output options.
Identify the problematic frequency using audio analysis tools or by ear, then input it as the center frequency.
No, this tool processes one audio file at a time for precise control over the filtering.
The bandwidth determines the width of the frequency band that is attenuated around the center frequency.
Yes, the audio file must be under 200 MB to be processed by the tool.
