This list represents only some small fraction of releases worked on by Alain. Last updated 2023.


The cost of mastering services offered represents the delivery of a master; specifically the administration work and studio time required, listening to mixes, potentially providing mix critique or other advice and producing and delivering one master inline with the best expert judgement of the engineer. It does not cover any subsequent revisions unless they are purchased either as part of a package or individually. Under normal circumstances, either all revision requests will be honoured or a full refund of the amount paid for the affected song will be made. Circumstances which shall be considered to fall outside the scope of normal include those in which the client requests revisions at some substantially later date after the engineer assumed the project had been concluded, and requests which are deemed by the engineer to be disproportionately time-consuming, outside the scope of normal mastering or otherwise unreasonable.

If for some reason the initial master is unable to be delivered within a timeframe agreed to be reasonable by the engineer, or before a deadline which was clearly stipulated in advance of payment, the client has the right to a full refund of the amount paid for the songs which have not been delivered.

Concerning the liability of DDPs: a high degree of care is taken to produce high quality, error-free DDPs but the client must double-check the accuracy of the track order, track markers and CD data before sending the DDP to be manufactured. Especially where the artist makes changes to the track names, track order or has confusing file names, care should be taken to ensure no confusion of the track order or names has occurred at some stage. Neglecting to check a DDP before sending it to be manufactured and subsequently finding an error (wrong track order etc) on the finished CDs will not be deemed a failure of the engineer and no liability will be accepted. Liability will be accepted up to the total value of the mastering fee of the project if there is any error found demonstrably caused by the engineer which falls outside the expected scope of checking by the client (audio glitches etc).

When two versions of a track are deemed by the engineer to be trivially different, then they will be priced as one single track, that is the additional version will be free of charge. An example of such a case is when there is a full version and an additional radio edit version which is identical in every regard to the full version except the fact that it is edited down in length. In such a case, there is normally not a significant amount of work required to produce a master of this radio edit because everything is sonically identical between the two versions. If however there are three versions of a song, say the studio version, a remix and a demo version, and all of these are importantly different in terms of sound, such that different EQ and dynamic settings are necessary during the mastering process, then these are viewed as three different tracks despite the fact they may all be called the same thing

"Vinyl files" means a set of files which can be sent to your chosen facility to be cut for vinyl manufacturing. This does not include the actual cutting or pressing itself, they are just the files to be sent to be cut elsewhere. Generally speaking the files mainly differ from the approved digital masters only in that they are 2db quieter, may have a stricter phase coherence or may have certain frequencies more strictly dynamically controlled if deemed necessary. Regardless of whether vinyl files are offered as an included part of a package or purchased as an add-on service, they are provided only after the digital masters have been approved. As such, if after approving the digital masters and requesting the vinyl files the client changes their mind and requests new revisions of some kind and another round of vinyl files is required to reflect these revisions, another round of vinyl files will have to be paid for at the going rate.

Infinite backups are not provided. It is assumed that after a month of project approval, the project can be deleted. However, a good amount of backups exist for projects even up to a few years old. Software changes over time. One example is the Catalina update breaking anything 32 bit. Other software updates may pose additional challenges for opening old sessions. More issues may occur as a result of the fallible nature of file archival. This is why requests in respect to historic data retrieval are often fruitful but no guarantee can be offered.

Ordering mastering constitutes an agreement to the terms on this website in the English language. If you do not understand any aspect of these terms you should seek clarity before placing an order.   & - © Alain Paul Mastering 2024
