Processor

The Processor applies common audio processes to documents or selections within. To apply a process:

1. Choose the process from the pop-up at the top of the Processor. The panel will display the parameters for that process.
2. Configure parameters for the process.
3. To apply the process to a selection only, select "Selection only."
4. Click the "Process" button.

Processor > Change Gain

This process changes level by the value set by the slider. Enter specific values in the text box next to the slider.

Processor > Normalize

This process changes maximum or RMS level to value set by the slider. Enter specific values in the text box next to slider.

Processor > Invert Phase

This process inverts phase.

Processor > Trim

This process removes audio from the beginning or end of an audio file below a given threshold. The slider adjusts the threshold (in dB) below which audio is removed. Enter specific values in the text box next to slider.

To remove audio from the beginning of the document, select "From beginning below...". To remove audio from the end of the document, select "From end below...". Both can be selected at the same time.

To trim audio at the nearest zero cross (to avoid clicks), select "At Nearest Zero Cross". To preview the trim area, choose Waveform > Trim. Trim areas are shaded in red.

Speed

This process changes speed and/or pitch. Wave Editor has two converters: iZotope SonicFit and Apple AUTimePitch. Select a converter by selecting it in the "Converter" pop-up menu.

Processor > Speed > Time

This process modifies the length of an audio file. The length of the "Initial range" will become the length of "Result range."

To process time:

1. Enter a length into the "Initial range" field. Optionally, you can choose a preset in the pop-up menu to the right of the field.
2. Enter a corresponding value into the "Result range" field.
3. Click the "Process" button.

The "Initial range" and "Result range" fields use the chosen time units for the active document.

To retain the pitch of the audio, select "Retain pitch."

Processor > Speed > Factor

This process increases or decreases speed by the factor set by the slider. Enter specific values in the text box next to the slider. Higher values decrease speed, lower values increase speed. To retain the pitch of the audio, select "Retain pitch."

Processor > Speed > Tempo

To change tempo:

1. Enter a tempo in "Initial tempo" field. Optionally, you can choose a preset in the pop-up menu to the right of the field.
2. Enter a corresponding value into the "Result tempo" field.
3. Click the "Process" button.
4. To retain the pitch of the audio, select "Retain pitch."

Processor > Speed > Cents

This process changes pitch in cents. Use the slider to change the speed of the audio in cents (100 cents = 1 half step). Enter specific values in the text box next to the slider.

Processor > Speed > Key

This process shifts pitch by changing the given musical description in octaves and intervals.

To change key:

1. Choose the number of octaves to shift in the "Octaves" pop-up menu. You can shift up to 4 octaves.
2. Choose an interval in the "Interval" pop-up menu.
3. Choose the direction of the shift by clicking "Up" or "Down".
4. Click the "Process" button.

Pitch

This process changes pitch. Wave Editor has two converters: iZotope SonicFit and Apple AUTimePitch. Select a converter by selecting it in the "Converter" pop-up menu.

Processor > Pitch > Cents

This process changes pitch in cents. Use the slider to change speed in cents (100 cents = 1 half step). Enter specific values in the text box next to the slider. To retain the original speed, select "Retain speed."

Processor > Pitch > Interval

This process shifts pitch by changing the given musical description in octaves and intervals.

To change interval:

1. Choose the number of octaves to shift in the "Octaves" pop-up menu. You can shift up to 4 octaves.
2. Choose an interval in the "Interval" pop-up menu.
3. Choose the direction of the pitch shift by clicking "Up" or "Down."
4. Click the "Process" button.

To retain the original speed, select "Retain speed."

Processor > Reverse

This process reverses audio.

Processor > Remove DC Offset

This process removes any DC component from audio.

Processor > Convert Sample Rate

This process converts sample rate. To convert sample rate, select a sample rate from the "Sample Rate" pop-up menu. Wave Editor provides two sample rate converters: iZotope 64-bit SRC and Apple AUConverter. The pop-up contains a list of industry-standard sample rates. Alternatively, you can enter a custom value in the text box. To make the customized value stick to the text box hit the Tab key after you enter it.

To change the sample rate in the file header without actually converting the sample rate of the audio, deselect "Resample."

Advanced options are available for the iZotope 64-bit SRC. To edit advanced options, click the disclosure triangle labeled "Advanced options." Several presets are available in the menu. Use the sliders to modify filter steepness, cutoff scaling, and preringing. Enter specific values in the text box next to the sliders.

Processor > Dither

This process applies dither. Wave Editor utilizes iZotope's industry-leading MBIT+ Dither.

To apply dither, choose a range and type from the pop-up menus at the top of the panel. To view advanced options for Type I/II or MBIT+, click the disclosure triangle at the bottom of the panel. When you are ready to apply dither, click the "Process" button.

For detailed information on MBIT+, please download iZotope's comprehensive dithering guide.

Processor > Thresholds

This process allows you to create new Labels at audio thresholds in the active Layer. There are three sliders:

• Attach Threshold (dB)
• Release Threshold (dB)
• Interval (milliseconds)

Adjust the sliders as desired. Enter specific values in the text box to the right of the sliders. To preview results, choose Waveform > Thresholds. Label previews will flash red over the waveform as you adjust the sliders. Select the desired Label type using the radio buttons. Options are Markers, Regions or Slices. To snap new Labels to the nearest zero cross, select "At Nearest Zero Cross".
