Product FAQ

Common audio formats open directly: WAV, MP3, MP2, FLAC, M4A/AAC, OGG, Opus, WMA, AIFF, AU, CAF, AMR and many more, plus raw and telephony formats. You can also open the soundtrack of MP4, MKV, MOV, AVI, WebM and other videos. A recognized extension does not guarantee that every codec or protected (DRM) file inside it can be decoded.

Choose Convert / Export, select MP3, set the bitrate (192 kbps is a good default for music, 128 kbps for speech) and choose a folder. MP3 export is included and free. To export only part of a file, select it first and use Export Selection.

There is no built-in time limit. The practical limit is your free disk space and memory. For very long sessions, save your work regularly and turn on auto-backup.

Most often the wrong input was selected, or Windows blocked the microphone. Check Settings › Privacy & security › Microphone, pick the correct device in the recorder and watch the level meter before you press Start. To capture computer sound, choose the playback device you actually listen on. See how to record audio.

No. The program has no vocal or stem separation. Tools that try to cancel the centre of a stereo mix also remove other instruments placed in the centre. Noise Reduction and Repair Studio are designed for noise and damage, not for separating voices from music.

You can record any stream that plays through your speakers by choosing your playback device in the recorder. The current version has no scheduled (timer) start, so start and stop the recording yourself. See how to record computer sound.

The file probably uses a codec or protection that the decoder does not support, even though its extension is on the supported list. Try converting it to WAV with the program that plays it, then open the WAV.

Yes, for MP3 files. The ID3 Tag Editor sets title, artist, album, year, genre, track, comment, lyrics and a cover picture and saves a tagged copy. See how to edit ID3 tags.

Not inside the current version, which no longer includes a CD ripper. Rip the CD with Windows Media Player Legacy, then edit or convert the tracks here. See editing tracks from a CD.

If a whole recording plays too fast or too slow, for example a tape digitized at the wrong speed, use Speed / Playback Rate or Speed Up / Slow Down on the full file. The program does not automatically correct wow and flutter that changes from moment to moment.
