How can I provide the audio for my cassette production?
For the best quality you should provide your audio as either WAV files, a DDP file or on master CDs (please send two master CDs, one for side A and one for side B), however you can also supply us with MP3 files if you prefer and whilst the quality of MP3s is not quite the same as a WAV file as MP3s are always compressed to some extent, it is unlikely to be noticeable in cassette duplication if supplying us with higher quality MP3s. If you do send over digital files, please either clearly label them with the track order and which side they are on or supply them in separate folders for side A and B.
We don’t recommend sending AIFF files as they sometimes do not come out as intended or just produce a static hiss, whilst we tend to also avoid FLAC files as they are prone to erroring.
Sending us your files
Please use whichever method below is most convenient for you:
1. Uploading via Dropbox 
Just upload your artwork and/or contents into a folder within your drop box account and then share the dropbox folder with this email address: [email protected]
2. Uploading via WeTransfer 
To upload large files (if you can zip all of your files into a single zip folder that you then upload to Wetransfer then it will help us to save time when downloading and avoid files being missed) via WeTransfer, please upload them to us here: http://www.bandcds.wetransfer.com
3. By Post
You can post your content and artwork files to us at the following address (please enclose two identical copies of the data files being added to the disc so that we can verify them against each other to check for scratches):
Disc Production Manager
Wizbit Internet Services Ltd
Keppel K1
Daedalus Park
Lee-on-the-Solent
Hampshire
PO13 9FX
Please remember to include a note with your master files informing us of your name, contact and delivery details, the type of discs that you wish to order, the type of packaging you would like and how many items you wish to order.
We will then check the files and contact you back if we have any questions, or prepare and post the proof disc to you if we don’t have any questions.
4. Email us the files
Please email the artwork and content files (if they are being burnt by us) to us at [email protected]
Just note that if the files come to over 10MB then you may need to send them to us using methods 1-3 above, by Dropbox, YouSendIt or by post.
Please contact us for further information.
