The Studio

Founded in mid 2016 in Madrid, Spain, The Empty Hall is a studio specialized in extreme metal productions. From demos to full-lenght albums, we are willing to adapt ourselves to a wide range of needs and artistic expressions and obtain the maximum potential from each project.

In the short period of time since the opening of the studio, we've had the pleasure of working with bands such as Selbst, Cryptic Wanderings, Aversio Humanitatis, Siberian Hell Sounds among others. But we're still newborns and in full expansion, continue to research on our website and listen to our works...


Featured works

Bands / Labels



The best and most straight way to obtain artistically expresive results with the exact sound you want is to work together from the early stages of the production, discuss what kind of production the band is looking for and consider the available resources.

(Online) Mixing

If your album was recorded elsewhere, you can send us all the tracks and be confident we'll work hard to obtain the best possible results. We'll mantain constant communication, sending references and making pertinent revisions.

(Online) Mastering

Send your songs for a final revision and enhancement. We'll improve the balance and response the material will show in different sound systems, and it will be ready for CD/Vinyl/Cassette duplication or streaming.
*We do Vinyl-mastering*

Drum Editing

We can prepare your drum tracks for mixing: Time alignment, toms tracks cleaning, snare bleeding reduction, check phase coherence and create MIDI files for kick and snare.

Guitar Reamp

Whether it is for availability, distance issues, or you just prefer to record your tracks on your own, we can re-amplificate and record your guitar tracks and give it a proper sound. All you have to do is sending us the DI tracks.

Prices for mixing really depends on the lenght and complexity of the project.
To fix a budget we should first discuss about number of songs, the kind of production you are looking for, is drum editing or reamping needed?, how was the album recorded? etc.
I strongly recommend to get in contact before you start the recording process.

Approximate budgets would be 250€-400€ for an EP (under 25 min) and 450€-750€ for a full-lenght, this includes mastering.


It can vary depending on the availability and schedules of the band and the number of sessions needed (the more sessions the lower the price), but it's usually arround 80€-100€ for a working day.
