What is the purpose of the WaveCache.wfm file?

The WaveCache.wfm file serves a specific purpose related to the visual representation of audio within Pro Tools. This file contains waveform display data, which is essential for how audio tracks appear in the Pro Tools interface. When you load a session, the software uses the data stored in the WaveCache.wfm file to quickly render the waveforms of the audio files included in your session, thereby enhancing the visual workflow and allowing for immediate access to the graphical representation of audio data without needing to regenerate it each time.

This is particularly crucial for larger sessions, where generating waveforms from scratch can be time-consuming. Having pre-existing waveform data allows users to navigate their sessions more efficiently, enabling faster editing and arrangement of tracks. Hence, the mention of this file in the context of its purpose being to store waveform display data is accurate.
