Mastering follows on from the editing process. Again a sophisticated Sequoia-based digital audio workstation is used.
Two main activities are done at this stage – final audio processing and preparation of a Pre Master CD. Final audio processing typically
includes trimming the beginning and end of each piece, inserting fade-ins/outs, adjusting the overall level of the pieces, and potentially
addition of artificial reverberation using high quality hardware and software - including Bricasti M7, Sequoia's Room Simulator
and Altiverb from Audio Ease.
Sometimes other dynamics processing (multi-band compression and equalisation) may be needed to
fix problems or to adjust the tonality and balance of sound - although for classical recordings such processing is used very sparingly
if at all.
Once final audio processing is complete the pieces are sequenced into an agreed order and an appropriate amount of silence inserted
between each. The final step is to produce a pre-master CD where ISRC, UPC and PQ code editing is performed and all tracks rendered
to CD-R in accordance with the Red Book CD standard. High quality sample rate reduction and dithering algorithms (e.g. POW-R)
ensure that reduction from the high sample rate and bit depth used during recording down to the 44.1KHz and 16 bits required by the
Red Book standard is performed as transparently as possible.
The end result is a professional pre-master CD-R that can be sent
to a CD pressing plant if necessary for production of a glass master from which CD’s can be made. Small CD-R based duplication runs
of up to 10 copies can be handled in-house however larger runs and any associated artwork, including CD and case insert printing are
