Mastering Studio

This is an older photo from 2008, but I still like it. Today the hair is grey, the room and the monitors are bigger and the work is still overwhelming. Every now and then something still has to be soldered....



 Mastering per song:  from EUR 65,-  (depending on track's length) -

 STEM-Mastering per song:  from EUR 95,-  (depending on track's length and effort)_

 Complete mix per song:  EUR 150,- to 350,-  (depending on type & number of tracks) -

 DDP master incl. PQ-coding, checksum, upload etc.:  EUR 110,- -

 The first step is a non-binding test mastering of any title, so that it becomes clear what the mix has to offer and where there are still weaknesses. If such weaknesses are identified, advice is given on how they can be corrected.

There is no room for nitpicking and compromises in music, there are no hourly rates and hidden additional costs, but clear prices (see above), which are set together before work begins. Flat rates and volume discounts are possible. The customer receives audio copies that they can check in their own familiar situation and compare with other productions. A joint decision is then made: if the customer wants changes, these are made at no extra cost, regardless of how many are necessary. The final master is only created when everyone involved is grinning with satisfaction. This is the only way to do justice to the music and really bring it to the fore.

Frippery like MP3 / FLAC / M4A conversion, creating 16-bit files or putting everything together in the correct order as a WHF for checking doesn't cost anything extra either.

The basis for sound optimization is the quality of the supplied material. Mastering intervenes in the frequency response and compression in order to adjust the sound to the desired listening habits and references. The better the mix is, the better this works. If the ratios, individual sounds and frequency response are already roughly in tune and have not yet been pre-compressed, the mastering usually achieves the optimum as the final fine-tuning. If a mix has weaknesses, mastering only partially conceals them or even emphasizes them. Therefore, the first step towards efficient mastering is a competent assessment of the source material.

The saying "we'll get everything under control during mastering" is just as nonsensical as the eternal studio lie "we'll do the bass drum sound later in the mix". Every craftsman knows that the end result depends on the preliminary work. That's why Eroc always works in partnership and constructively with the "foremen" and gives advice on what may need to be changed in the mix to achieve the optimum result. If this is still not satisfactory, Eroc can also be booked for the final mix. The highest premise: Bands, artists and producers are the best "mastering team" together with Eroc.

These formats are available here: DDP files via DSL directly to the pressing plant, audio CDs for simple copies, ISRC code, UPC/EAN, CD text, video sound format and more. The results also meet the requirements for "Mastered for iTunes", and Eroc has the necessary Apple certificate.

Processing in CubeTec systems, where tools with the technically best digital resolution and sampling rate of 24 bit (32 FP) / 384 kHz are used, are the prerequisite for optimum results.

The EMR Firebrigade

A well-know situation: you're sitting for hours or even days in a mix and your head is swirling. Is the bassdrum loud enough? Are the vocals too low? Should I use more compression? No problem thanks to the new Mastering Firebrigade at EMR: just a phone-call or an email to us, then upload a track onto our server and in about half an hour everything will be fixed - the mastered track is on the server ready for download, so that you then can easily judge how it sounds when mastered. And in addition you'll get some real good advice from an objective professional, because in this particular situation the "third" ear of an experienced colleague is worth more than pure gold.

This service is free for all regular EMR customers - and another good  argument to become one...





Again another celebration-year!

On December 2nd the concert from Grobschnitt at WDR Rockpalast (TV) is released finally on DVD in a box, together with a brandnew remix of "Solar Music Berlin 1978), completely remastered by Eroc from the original analog tapes.

Eroc's knowledge and power occurs from decades of experience as musician on stage and as engineer and producer in the studios. Since the 60's Eroc profession is mainly music and recording, which brought him into close cooperation with many popular bands and personalities, whose listings here would blow up the party. Already in 1971 he joined recording and mixing with the legendary Conny Plank, leading into a close friendship and many productions for both of them. He also worked with people like Dieter Dierks and Walter Quintus in the 70s and today still helps his friend and colleague Mack (Queen, ELO etc.) with his mixes. Another argument for his work is his flexibility in many different genres. From restoring old recordings from the 20's, 30's and 40's up to bands of the 60's, 70's and 80's - from audiophile arts over to Punk, Hip Hop, Stoner-Rock, Kraut-Rock and the heaviest Metal, from classical operas and piano-concerts to radio-shows and commercials Eroc has treated in the passed 13 years nearly everything imaginable. And always up to each customer was fully satisfied.

Anything more to say? No. You better shut up 'n listen. Meanwhile Eroc's name is to be found and his work to be heard on millions of CDs and vinyls worldwide...
