In the second labelled section, the waveform is clearly clipped. It is not actually clipped, but is dangerously close to clipping. In the first labelled section, the waveform just touches the top an bottom of the track. Here’s a couple of screen shots, first with clip indicators turned off, then with clip indicators enabled: Just as the red clip indicators may be visible when there is actually no clipping, so there can be clipping without the red lines showing. Preferably that will be in a “lossless” format such as WAV or a CD. If it sounds OK, then it IS OK.įor any type of “sound restoration”, it is always best to start from the best quality original that you can get. If your recordings are MP3s (or other lossy format such as WMA or AAC) then probably the best thing is to just leave them as they are - although you may be able to fix the clipping to some extent, if you then re-encode in a lossy format, there will be further loss of sound quality, so the net result will probably be no better than you started with.Īt the end of the day, your ears are your best and most important guide. When making an MP3 from an original recording, it is advisable to allow a couple of dB “headroom” to allow for this.īecause MP3 is a “lossy” (inexact) format, encoding always loses at least a little sound quality. This is because MP3 is not an “exact” representation of the original audio, but just a close approximation. If the audio is then encoded in a lossy format such as MP3, that can cause the peak level to go a bit above 0 dB. This can cause large parts of the audio to be very close to 0 dB. If it sounds OK, then you can just use the Amplify effect (or “Normalize” effect) to bring the level down a little and it’'ll be OK.Ī lot of modern recordings are maximized as loud as possible (see “ Loudness War”). It is a warning that the audio may be (and probably is) clipped. The red lines don’t mean that the audio is definitely clipped.
