Transport Window<br />

The Transport window is a floating, re-sizable window. It<br />

contains three areas: a time display showing elapsed<br />

time, the Transport controls (Return to Zero, Stop, Play,<br />

Go to End, Record, and Loop during playback), and<br />

audio level meters with clip/peak indicators.<br />

Time Display<br />

The Time Display is like a counter. It shows elapsed time<br />

and tracks the “playback head” as audio plays. Clicking<br />

on the waveform when playback is stopped will cause<br />

the current cursor location to appear in the Time<br />

Display. This display will also show the time remaining<br />

while performing Open, Save or DSP processing actions.<br />

Clicking on the counter will bring up the Go To Time dialog,<br />

allowing you to type in a time location – when you<br />

click OK, <strong>Peak</strong>’s playhead cursor is inserted at the<br />

Meters<br />

<strong>Peak</strong>’s meters are much like the VU or LED meters on a<br />

mixing board or tape recorder. They are bar graph<br />

meters that show the relative volume or loudness in<br />

decibels (dB), of audio as it plays. They are also<br />

designed to show peak volume and whether the signal<br />

has “clipped,” or distorted.<br />

You can configure the Meters display by choosing Meters<br />

from the Audio menu, or by clicking the appropriate button<br />

in the Toolbar. Using the Meters dialog, you can<br />

select the <strong>Peak</strong> Hold time and Clip Indicator Hold Time.<br />

The <strong>Peak</strong> Hold indicators appear as yellow bars at the far<br />

right of each of the bar graphs as audio plays, and selecting<br />

a hold time causes the indicator to pause for easy<br />

reading of the peak value during playback. The Clip<br />

Indicators appear as red bars at the far right of each of<br />

the bar graphs as audio plays, and are triggered when<br />

audio distorts, or “clips”, and selecting a hold time causes<br />

the indicator to pause for easy reading of any clipping<br />

or distortion that occurs during playback. Setting the<br />

<strong>Peak</strong> Hold and Clip Indicator Hold Times to None turns
