VidiEditor allows one to set specific shape tags as audio proxy format. All items having this shape defined will be found in the VidiEditor search. Compared to the video proxy format where a specific shape is mandatory, the audio proxy format is optional. If an item has following specificity it will also be found:

Shape: Original

Codec Family: AAC

Media Type: Audio (no video component)

It is still recommended to set a shape tag for audio-only files as it clearly specifies a usable file.

Format Specification

Due to the playback in VidiEditor source and timeline players, the usage of audio-only in VidiEditor is limited to:

Container: MP4, M4A

Audio Codec: AAC

Samplerate: 48 kHz, 44.1 kHz

Bitrate: 192 kbps

Channels: up to 8x stereo

These parameters are also used for recordings done on voice-over recordings. A suitable shape tag will be added during the installation:
