Auto Offset Removal
Menu Command: Effect | Filter | Auto Offset Removal
Auto Offset Removal automatically removes a vertical shift or dc offset in the waveform. Offsets occur when audio is wired through several external devices that do not share a common ground. Computers with sound hardware integrated into the motherboard can have significant offsets as well. If the waveform is constantly above or below zero during silence, then it has an offset that must be removed. Offsets can cause pops and clicks between edit points and other problems if not removed.
Unlike Effect | Offset, this effect does not need to scan the entire selection and offsets cannot be set to specific values. Values to cancel out existing offsets are automatically calculated and used. Even varying offsets are removed.
Duration for offset calculation
Controls how long to analyze the audio for an offset. For constant, stable offsets, set this value to the maximum. For fluctuating offsets, use lower values.
