Main Free Mp3 Editor:

|
New: Click to create a new file.
|
Open: Open an existed file to edit.
|
Save: Save an edited file.
|
Options: Where you can change the output path, set specific parameters, change the display colors and so on.
|
Copy: Copy a selected section of a track.
|
Cut: Cut a selected section of a track.
|
Paste: Add a fragment to a track, which will increase the length of the track.
|
Paste mix: Paste a fragment to a track and mix with the original audio.
|
Undo: Cancel the former actions.
|
Redo: Resume the actions that have been cancelled before...
|
Zoom in/out/full: Ways of displaying a selected section.
|
Amplify+/-: Applying Amplify+ to the selected audio segment will increase its volume (from 100% to 200%); while using Amplify- helps to decrease volume (from 100% to 0db).
|
Fade in/out: When your recording begins or ends with special effects, for example, applause, you need to use fade in or fade out to connect the special effect and the audio. Select a segment of the track, set fading Proportions for the volume’s starting and ending, the fade in/out effect will be easily completed.
|
Normalize: This function enables you to set a desired peak level for the file or selected segment to rise. When set to 100% or 0db, normalization allows you to achieve the greatest amount of amplification that will not result in clipping (distortion). All parts of the wave are amplified at equal levels.
|
Insert silence: Key in a definite time of silence and insert it into the point where the slider locates. This command is helpful when you need to separate contents of an audio without splitting them to different files.
|
Silence:
Unlike deleting or cutting a selected segment, silence leaves the duration of the selection intact and simply zeros the amplitude within it.
|
Invert: This command is to invert the waveform samples, that is, all positive offsets are negative and all negative offsets are positive. Inverting doesn’t Produce an audible effect, but it can be useful in lining up amplitude curves when creating loops or pasting.
|
Flanger: Flanging has a very characteristic sound that many people refer to as a "whooshing" sound, or a sound similar to the sound of a jet plane flying overhead. Set parameters such as delay rate, mix depth, feedback grain and so on to add the special sound to your audio.
|
Vibrato: Add vibrato effect in the sound. Adjust the depth, frequency and phase of sweeping to get the best vibrato effect.
|
Delay: Delay effect can be reached by setting the time, mix depth and feedback grain. It is easy to add this effect to the selected segment.
|
NF: Notch filter. Use this filter when you want to remove very narrow band frequencies.
|
HPF: High pass filter. It attenuates frequencies below the specified cutoff frequency and lets you hear high frequencies only.
|
LPF: Low pass filter. It blocks higher frequencies and lets you hear low frequencies only.
|
HSF:
High shelf filter. It boosts or cuts frequencies above the cutoff and passes frequencies below the shelf cutoff with no change made to their gain. Use this filter to enhance or diminish any adjustable amount of high frequency material in a sound.
|
LSF:
Low shelf filter. It boosts or cuts frequencies below the cutoff and passes frequencies above the shelf cutoff with no change made to their gain. Use this filter to enhance or diminish any amount of low frequency material in a sound.
|
Play: Play an audio file or a selected audio segment.
|
Stop: Stop playing an audio file or a selected audio segment.
|
Pause: Pause playing.
|
Loop: Play the selected segment repeatedly without stopping. If there’s no segment selected, the audio will be played from the location of the slider.
|
Play to end: Select an audio segment. The difference between Play and Play to end is that, the former Process will stop at the end of the selected segment, while the latter Process will not stop until it reaches the end of the audio.
|
Continue: When you pause an audio, you need to click the Continue button to resume playing. The Play button will not help to resume.
|
Information: Information of the file will be displayed on bottom part of the editing interface. Click Inf. Button to read more.
