For your convenience, we will set you up with an account on our specialized CMS, GloZone, through which you will be able to upload your audio to us directly. We suggest uploading an MP3 file directly to this client portal. However, we can work from any other audio source, be they digital – MP3, MP4, WAV, WMA, AAC or physical, such as CDs and cassettes and we are always available to discuss any technical issues with you.
