Audio Recording

If you are mastering your own CD for replication or duplication, you might need to assess whether your CD writer (drive) and your media are the best ones for audio CD mastering applications.

Let’s start with some theory and facts:

a.) The higher your burning speed, the more likely jitter will happen. These jitters are undesirable errors that can affect audio quality. Read here more about the relationships between jitters and CD burning speed: http://www.myce.com/article/CDR-Audio-Quality-Vs_-Burning-Speed-189/

b.) Old CD writers can write very low speed; for example 1x to 4x.

c.) Modern CD writers can write very fast (e.g) 52x however optimum writing speed (lowest jitters as possible and best recording quality) can be estimated around 4x which most mastering engineers in the industry suggest.

d.) Quality of the burn master CD is dependent on CD writing speed, quality of the media and the quality of writing software/red book CD software. Of course, the overall sound quality is dependent on the output of the mastering engineer.

Basic Requisites-your professionally mastered audio

Lets not discuss about CD writing software (red book CD mastering software) or how does the mastering engineer do the mastering. If you are interested in this topic, you can read this tutorial on how to make a CD master that complies with red book standard.

Commercial audio CD released are different from the mix you have in your own home recording studio. In this article on characterizing a professionally mastered CD; you will know that if you extract the audio from CD, the waveforms are obviously bigger (which means louder) than a raw mix.

Therefore; it is imperative that you need to have your mix professionally mastered before you think burning it to a CD and selling it.

Selecting the best CD writer and media

Lets see how you will be able to select the best CD writer and media for home audio mastering use.

Most professional mastering engineers agree that the best CD burner/writer for mastering is Plextor. The recommended model is Plextor PX-716A – Disk drive IDE Internal CD Writer if your computer supports IDE based drives. Unfortunately, IDE based drives are not popular today and replaced by SATA technology. So I would recommend you look for a SATA alternative (will be provided later).

If you are looking for a SATA based CD burners/writers, you can have the Plextor PX-716SA DVD+\-RW Dual LayerSerial ATA Drive

As to the reason why most mastering engineers recommend Plextor it’s because of its negligible jitter rate (errors) and high quality set of CD tools that you can used to check the errors present in the CD media. It is important that the master CD you will be submitting to the replication/glass master plant should be completely error free.

There are instances that the CD submitted for duplication or replication will be rejected if the error rate is very high. This is why its important that you burn the CD in a writer with very low jitter.

Plextor has the set of tools that you can used to check if your CD master is error free or not. This is very convenient for you.

These drives support burning of CD master at 4x which is the industry standard for burning CD masters. So if you are using these drives; it is highly recommended that you will burn the CD audio master at a speed of 4x using Red book CD audio mastering software such as Sony CD Architect 5.2

Recommended CD Media for CD master: Again most professionals in audio industry appreciate the quality of Taiyo Yuden CD-R.

These CD-R media has the lowest BLER,E-12, and E-22 errors in the CD media industry. These errors are critical if you are creating a audio CD master, it is because these errors can seriously affect the audio quality output of your CD master.

The maximum rated speed of these CD-R is 52X although, you can create a CD master at a speed of 4X using Plextor drives.

It is recommended to backup your CD master so that you can reuse it easily if you need to replicate again your work. You also need to backup your original masters (high resolution WAV file in 24-bits) so that you can easily use them to re-create another CD master.
