What are the audio requirements for cassette production?
Qrates accepts high-resolution, "Program Ready" digital audio files including WAV, FLAC, and AIFF.
The most optimal resolution and format is 44.1kHz/16-bit WAV files. Detailed audio submission guidelines are provided below from our partners at the National Audio Company.
Cassette Audio Master Guidelines
- If you need your project to enter production as soon as possible, you must provide program-ready audio files. What is a "Program Ready" audio file? Every cassette has two programs. Program A is Side A and Program B is Side B. Providing “program-ready” audio files means that if each side contains more than one track/song, the tracks are combined as one audio file for each side – tracks in the correct order with the desired gaps between. (Most artists prefer a 2 second gap between tracks.) Both programs should be in 44.1 kHz/16-bit format.
- Tutorials for preparing your master files to be program ready are available at these links: Tutorial for using Audacity for Audio, Tutorial for using iTunes for Audio.
- All masters should be accompanied by a track list or note detailing Sides A and B. Check your master carefully for playback errors prior to sending it to save the time and expense of replacement it is unusable. Sequence your master exactly as you want the final product to be with the gaps between tracks exactly how you want them. In particular, please pay close attention to the pre-track pause times and any tracks that have audio extending across the next track marker.
- If you are using iTunes, changing the file names alone is not enough to preserve your track sequence when we create the .wav versions necessary for editing your production master. You must also check the embedded track number info for all of the tracks you are submitting to NAC. The quickest way to check this is to go to the View menu, select “View Options,” and add a check for “Track Number.” Then you can check the songs in your library for the proper embedded track number data, and if the sequence needs to be changed you can select a track, go to File > “Get Info” and fix the track number in the “Info” tab.
- Sometimes pops will occur between these tracks when a ripped/ compressed format has been used. For best accuracy, prepare Program Ready files, and check for these issues.
- De-essing may be applied when the master provided is overly sibilant or bright, and you have not ordered cobalt/chrome tape. This helps reduce high-frequency distortion, and allows the program volume level to be optimized for cassette tape. All efforts are made to keep the process as transparent as possible.
