Quality control is an important step of CD duplication, CD replication, DVD duplication and DVD replication process. When we first receive a customer’s master, it is checked for playability on a DVD player, computer and stereo. We look for errors in menu navigation, skipping, freezes in video, extreme audio levels. The disc is inspected for physical damage such as scratches and dust. Customers are notified of any potential problems before we start actual production. The duplicated or replicated discs are randomly checked under the same guidelines to ensure consistent quality.
In large run replication, specialized machines are used to verify data on the discs by comparing the 1’s and 0’s of the discs, to ensure the highest level of quality among the thousands of discs that are being produced.

With double layer blank DVDs (abbreviated as DL DVDR here) it allows longer videos to be placed on a single DVD. Is it possible to duplicate a DL DVDR like a regular single layer DVD? While DL DVDR has been around for a little while, there are not many choices in the brand of media, and some media tend to have compatibility issues in older players. We would suggest against making mass duplication of a DL DVDR master; instead opt to compress the entire disc to a single layer DVD for DVD duplication, or split the content onto a 2-disc set.

CD audio files come in many formats today, there is the most common mp3, mp4, and also the AIFF and WAV. Which one is the best format for CD duplication and CD replication? Let’s start with talking about the different file formats that can be used to create an audio CD:
MP3 and MP4 are compressed formats that are most popular with online downloads, however not the best choice and quality for duplication and replication.
AIFF is commonly used on Macs and is an uncompressed audio file format that provides excellent sound quality.
WAV is a comparable format that is mostly used on PCs, still an uncompressed audio file format and tends to be large in size.
Therefore, making an audio CD master from AIFF and WAV will preserve the best sound quality. When making a CD master we should always burn as an audio CD, not data CD. Most CD burning softwares today will convert the mp3, AIFF or WAV into an audio CD format when it is set up as an ‘audio’ CD. An ‘audio’ CD will play in any home, car stereo and computer, while a ‘data’ CD containing MP3, AIFF or WAV files will only play in computers and stereos that are equipped to play audio files.
