FAQ - Frequently Asked Questions

Which is the ideal source format for mastering, and in which format will I receive my mastered material ?

Currently, we only accept WAV and MP3 files (AIFF is in preparation). MP3 is lossy compression process and thus, not ideal for mastering. If you want to supply us with MP3 files, please make sure that they are coded in at least 192 kbit/sec (stereo, not joint stereo).

We recommend you send us your files as a WAV format, at sampler rates of 44.1 khz, 48 khz, or 92 khz and with a bit depth of 16, 24 or more.

You will receive a master as a 16 bit/44.1 khz WAV file, which is a common reproduction format, to make an audio CD. On special request you will receive your files also in other formats.

There are several free programs to convert AIFF to WAV:
e.g. Switch for Windows, see www.nch.com.au/switch
or SoX Wrap for Apple/Macintosh, see www.waveformsoftware.com/SoX_Wrap/soxwrap.htm

In Apple Logic Pro you can convert an aiff audio file under: Audio Window –Audio File– Convert to WAV Stereo

Do you master individual audio tracks or the mix ?

You provide us with your mixdown. Mixdown and mastering as two different procedures. In the mixdown you bring the individual audio tracks into the right relationship and, where applicable, add effects (delay, chorus, distortion, etc.). Everything that alters the total sound of the mix, is part of the mastering process (e.g. compression, dithering).

What happens, if I have paid for the mastering, but I am not satisfied with the product ?

Tell us exactly what you are not satisfied with. We will make a new master according to your wishes. If you then are still not satisfied with the results, we give you your money back. In no case do we want to have unhappy customers.

Can a data loss (sound loss) occur during the file transfer ?

No. Your transferred data is binary coded, our upload function checks that the data has been completely transferred.

How do I download the audio files to my Apple Macintosh ?

In the safari webbrowser, open the "data upolad" window in the "window" menue. Move the marked url with copy/paste in that window. The file is loading on your computer.

Do you have trainee openings ?

No.
