About this tool
Audio Editor is a free online tool. All-in-one editor: cut, join, change speed, reverse, adjust volume, fade and normalize.
After uploading the audio file, the tool displays a complete waveform editing interface. Supports basic operations: cut, copy, paste and delete. You can choose the area to apply the effect: fade out, volume normalization, noise reduction, equalizer, reverb, compression, etc. Support undo/repeat operation history.
Audio editing occurs in both the time domain and the frequency domain. Time-domain operations directly modify the sampling point data, and frequency-domain operations modify the frequency components through Fourier transform, and then perform inverse transformation. Noise reduction uses spectral subtraction to identify the noise spectrum and subtract it from the signal. The equalizer uses multiple bandpass filters to adjust the revenue for each frequency band.
Suitable for podcast post-production, music presentation editing, recording restoration, and sound design. Support multi-track mixing (superimposing multiple audios). Output to MP3, AAC, OGG and other formats. All processing is done locally on the browser to protect privacy.
The online audio editor provides functions such as cutting, copying, pasting, fade-out, volume adjustment, noise reduction, etc., and supports multi-track editing and effects.
