A FEW USEFUL ANSWERS

Before you download.

The details that help you choose the right tool and get started.

Need more help?

Is CyberPower Audio Editing Lab still a paid product?

No. The current version is free. Its audio editing and supported export formats do not require a paid registration.

Can I trim the start or end of a recording?

Yes. Open your recording, select the unwanted section in the waveform, remove it and preview the result before exporting.

Can I record and then edit audio?

Yes. Choose an available recording input, record your audio and edit the result in the same app.

Will editing overwrite my original file?

Keep the original and export to a new file when you want to preserve it. Always check the destination before replacing an existing file.

Can I record my voice and computer sound together?

The Record… window offers an option to capture both sources. Select the correct devices and choose whether to mix them to stereo or split microphone and system audio to left and right.

What should I check if the recording is silent?

For a microphone, check device selection and Windows microphone access. For system audio, start playback and choose the device used for that playback. Make a short test before a long take.

How do I save an edited recording as an audio file?

Use Convert / Export… to choose a supported format and save a playable output. Save to a new filename to preserve your original; an editor project is separate from the exported audio.
