Drag the files ContinentalDrift.wav and DeepTechHouse.wav into the upper half of the Match Volume panel. One application of Audition is to match levels to the broadcasting standard of -23 LUFS. On the other hand, a sustained sound, like distorted guitar, will have a high average level but low peak level.Īs a result, the International Telecommunications Union (ITU) has developed standard measurement protocols-the most recent being LUFS (Loudness Units referenced to Full Scale). A drum hit will have a high peak level but a low average level because once hit, the amount of energy decays rapidly. However, there are many ways to measure “level.” A signal’s peak is one indication of level, but so is a signal’s average level. This is particularly important for broadcasting, where some governments impose regulations defining maximum volume levels. It’s often helpful to match volume levels among different pieces of music. Close the File without saving it, and close the project without saving.Choose Effects > Silence to convert the audio to silence. Play back the selection, and you’ll hear reversed speech. However, if you play this, you’ll hear no audible difference. Note that the positive and negative sections are flipped, so the positive peaks are now negative and vice versa. Play the file to hear what it sounds like, and then select the part at the beginning that says, “Most importantly, you need to maintain good backups of your data.”.Choose File > Open, navigate to the Lesson04 folder, and open the file NarrationNeedsHelp.wav.Silence replaces the selected audio with silence. Reverse flips an audio selection so that the beginning occurs at the end and the end at the beginning. Invert changes the signal’s polarity (commonly called phase) and produces no audible difference. Loop repeats the selected portion of the audio when you click Play. However, you can still audition any changes before applying them, because most effects chosen via the effects categories have a Play and Loop button to the right of the effect’s power on/off button. Unlike the Effects Rack, editing is destructive (although the changes aren’t made permanent unless and until the file is saved). ![]() Clicking Apply applies the effect to the selected audio. Most effects chosen via the effects categories (Amplitude and Compression, Delay and Echo, etc.) have an Apply and Close button.You can use the Undo command to undo the effects. The Invert, Reverse, and Silence effects are applied to the audio as soon as you select them.Any effects you can also access from the Effects Rack work the same way when opened from the Effects menu, with three exceptions: ![]() This section covers effects that are available exclusively from the Effects menu. ![]() Unlike the Effects Rack, you can apply only one effect at a time. You can process any audio selected in the Waveform or Multitrack Editor by choosing the desired effect from the Effects menu.
