Reference Recording Audio with the Hard Disk Recorder Normalize Normalize raises the volume of the recorded audio to the optimum level. Use this to make the recorded audio as loud as possible, without distortion. Technically, this operation scans the recorded file for the highest level, then raises the volume of the entire file so that the highest peak is set to the maximum, non-distorting level. Normalization is calculated for the loudest signal found in either channel of the stereo recording and the same gain is applied to both channels. 1 Make sure that the Volume page is selected. 2 Press the [NORMALIZE] LCD button ([G] button). 3 At the prompt, press the [OK] LCD button ([G] button) to start Normalizing the file. To cancel the operation, press the [CANCEL] LCD button ([H] button). NOTE • Normalize can only be applied to a file that has been saved. If you haven't saved the recorded file yet, the display prompts you to save it before using Normalize. Undo/Redo When you make repeated changes to an audio file by overdubbing, the Undo function lets you quickly "undo" your most recent recording and restore the previous version of the data. 1 Make sure that the Rec Mode page is selected. 2 Press the [UNDO] LCD button ([G] button). The latest recording that you made is cancelled and the previous version is restored. Also, the [UNDO] LCD button changes to [REDO], letting you reverse the process and restore the latest recording. NOTE • Undo/Redo can only be used on a recorded file that has not yet been saved. Once you save a file, the [UNDO] LCD button is "ghosted" and cannot be used. • If you start recording by pressing the [REC] button and stop recording without recording any sounds, the [UNDO] LCD button is "ghosted" and cannot be used. ■ PUNCH IN OUT / PUNCH IN OUT (MERGE This method of recording can only be used on an existing recording. It allows you to rerecord over a specific part of the already-recorded material. You can replace the original part with the new recording by PUNCH IN/OUT, or keeping the original and mixing it with the new by PUNCH IN/OUT (MERGE). This lets you either correct a mistake in the recording or overdub new parts onto the original recording. Keep in mind that the parts before and after the Punch In/Out section are not recorded over and remain as the original data-they play back normally to guide you in and out of the recording. 1 Press the HARD DISK RECORDER [SELECT] button and select the recorded file to be re-recorded from the AUDIO Open/Save display. 2 Press the HARD DISK RECORDER [SETTING] button, then use the [TAB] buttons to select the REC MODE tab. NOTE • You can re-record over only one range at one time. NOTE • The beginning and ending of the recorded data using the Punch In/ Out function is faded in/out automatically. This is done to minimize possible noise at the beginning and ending of the recorded data. We recommend that you specify the beginning and ending points at sections in the data where the volume is low. 3 Use the [A]/[B] buttons to select a recording method.
