Supplying your master files for duplication or replication

This guide is to help you get your data files ready to send us that will be on your finished discs.

For a CD in audio format that plays on CD Players , HI-FI’s etc we’ll need from you either…

A disc image
This is a file that is basically an exact copy of how the discs will be manufactured and is our preferred method to receive the masters.
You would put the image together at your end with all the correct audio files, CD Text, track pauses ISRC codes etc and we make exact copies from the disc image.
This can be done in most disc burning software such as Nero / Toast etc
Image file formats for audio CDs that we accept are
DDP
bin / cue
NRG
Please note that iso image files are not used for audio CDs – only data discs.

If you are not able to supply a disc image we can put the master together for you if you supply the data audio files and any instructions for running order, CD text , ISRC codes etc

Our preferred audio file formats and specifications are

WAV – 16 bit 44.1 khz
Aif – 16 bit 44.1 khz
MP3

The maximum quality you can have on an audio CD is 16bit and 44.1khz sample rate. Please try not to send over higher rated files as it increases the file sizes, which can cause problems when transferring them over the Internet and we then have to convert them down to 16bit 44.1khz before production so the extra quality is lost anyway.

You can also post out a physical master disc for us to replicate or duplicate from, if you are doing so please use the best quality CD or DVD media you have available and burn at a slow speed 16x maximum is advised to avoid any potential burn errors.

CD / DVD Rom

If you are having discs in data format (mainly for computer use) you can also supply a disc image, which would be an ISO file. An ISO is a file that is basically an exact copy of how the discs will be manufactured and again is our preferred method to receive the master.

If you are not able to supply an ISO disc image we can put the master together for you if you supply all the data files to be included and any instructions for the discs.

If any of the above is not clear or you have any questions please get in touch and we’ll answer any questions that you may have.
