Audio Delivery Requirements
Prepare production-ready audio
Submit final, approved masters in the exact playback order for each side of the record. Audio should be clean, clearly named, and ready for cutting without additional editing.
01
Accepted master format
WAV files are preferred. Submit uncompressed, stereo interleaved masters.
Resolution
Use 24-bit audio at 44.1 kHz or higher. Keep every track in the same sample rate and bit depth.
Do not submit
Avoid MP3, AAC, streaming downloads, clipped files, watermarked references, or unfinished mixes.
Track order
Separate Side A and Side B. Number every file in playback order and make the filenames match the final track list.
Mastering and headroom
Submit final approved masters without clipping. Do not add extra normalization, limiting, or fades unless they are intentional.
Documentation
Include the final track list, side assignment, exact running times, speed, catalog details, and any cutting notes.
PROGRAM LENGTH GUIDE
Recommended maximum audio time per side
Longer sides can require lower cutting levels and may reduce overall loudness, bass response, or sound quality.
Use the recommended limits below when preparing your final masters.

Audio planning note:
Track sequencing, music style, low-frequency content, stereo width, and cutting requirements can affect what will fit successfully on each side.
If a side approaches the maximum range, contact the production team for review before submitting final audio.
Recommended folder structure
PROJECT_NAME / AUDIO / SIDE_A / 01_TRACK_TITLE.wav
PROJECT_NAME / AUDIO / SIDE_B / 01_TRACK_TITLE.wav
Use simple filenames with no special characters. Upload only the final approved versions.
Important: Side duration, groove spacing, bass content, stereo width, and playback level can affect the final cut. Follow the project limits shown in the vinyl wizard and contact the production team when a side is unusually long or demanding.
