1.
Enter the recording duration
Type the length of your audio in seconds. For a 5-minute recording, enter 300.
2.
Select the sample rate
Choose 48 kHz for video production work (the broadcast standard) or 44.1 kHz for music-only projects. Higher rates increase file size proportionally.
3.
Select bit depth
Choose 24-bit for professional recording (more headroom) or 16-bit for final delivery and distribution. 32-bit float is used for DAW exports.
4.
Select channel count
Mono is half the size of stereo. For video voiceover or podcasts, mono is often sufficient. For music or film soundtracks, use stereo or the appropriate surround format.
Why This Matters for Video Creators
Audio file size matters most when you're archiving multitrack recordings, delivering stems to clients, or planning the storage footprint of a long recording session. A 2-hour 24-bit stereo recording at 48 kHz takes up about 1.7 GB uncompressed — knowing this in advance helps you choose the right storage media and decide whether to deliver WAV masters or compressed AAC files. For video uploaded to vitelnk, the audio is packaged inside the video container, so your overall file size is dominated by the video bitrate rather than the audio.
