It is possible to edit and overwrite a waveform file even after registering it as a material.
At this time, if parameters such as the sampling rate or bit depth are changed, a discrepancy will occur between the waveform file and the material.
Even if a discrepancy occurs, it is usually not a big deal because the current waveform file contents are updated before preview playback or building.
If you want to immediately reflect the contents of the material after editing the waveform file, use "Local file synchronization".
For example, use local file synchronization when you perform the following operations.
