What key should be pressed to enable waveforms for audio tracks?

To enable waveforms for audio tracks in many digital audio workstations and audio editing software, the correct key is typically the Option key. Pressing this key triggers the display of the waveforms, which are visual representations of the audio signal, allowing users to see the amplitude variations over time. This feature is crucial for editing and mixing audio, as it provides valuable visual cues for making adjustments, such as aligning sounds, cutting, and fading.

The Option key, particularly on Mac computers, often serves as a modifier key that alters the function of other controls or commands, making it an essential part of the workflow in audio applications. Hence, it's important to know this key's role in enabling features like waveform display, which enhances the efficiency and accuracy of audio editing tasks.
