National Audio can work with almost any kind of media or digital audio file as the original for duplication. The most professional quality is achieved if you send .wav files that sound exactly as you like. The audio engineers at NAC make slight adjustments to make your recording sound its best on cassette tape. For more specific information click here.

Our turn-around time for cassette duplication orders is generally three to four weeks from the time we have received all the elements of your project: The three required forms, your audio master, and your album art files.

Rush orders are not available, but if you have deadline requirements call Customer Service to ask if your delivery date can be met.

Within a few days of the receipt of your project forms and files National Audio will email you a PayPal invoice which can be paid with PayPal or a major credit card. You must pay the invoice before we begin work on your project.
