The weight of analogue with digital precision.

 

A note from Tierra Audio's founders Javier and Esther...

At TIERRA Audio we LOVE analogue sound.

When we released the first analogue prototype of the Gravity VCA Bus Compressor in 2018, and the final version in 2020, the feedback from studios around the world confirmed to us that all our hard work had paid off: the Gravity delivered a powerful, musical and versatile stereo compression.

Since then, our love for analogue has expanded into an obsession over what digital technologies could offer. To take the sound and signal processing of the best analogue components, and combine them with digital control and programming got us excited about what the Gravity could become.

And we are blown away at the results.

The Gravity Mix & Master now brings the celebrated sound of our Gravity VCA Bus Compressor to the mixers and also to the world of Mastering, where accuracy and consistency are non-negotiable.

It offers new state-of-the-art tools along with significant innovations that we believe will change the mixing and mastering game as we know it, driven by the highest quality sound lovers who know what analogue electronics are capable of and who need truly efficient workflows in their daily studio and live work.

Esther Gutiérrez & Javier Pascual
TIERRA Audio Founders

 

The Gravity Mix & Master delivers THAT big sound with the best analogue components matched with revolutionary digital innovation.

Tierra Audio's in-house engineers have spent countless hours learning about what really matters, finding many multiple ways to improve the workflow of a modern recording, mixing and mastering studio.

More than 5 years of slow cooking.

 

In 2017, Co-Founders Esther Gutiérrez & Javier Pascual took their first steps on the path of 'pro audio hybridization', with the goal of efficiently merging the analogue and digital worlds.

More than 5 years later, Tierra Audio are proud to say they've reached their goal of providing music producers and recording engineers with the first of many hybrid tools, designed to act as an inseparable ally for high-end studio production.

Whilst Tierra Audio was founded on a love for the irreplaceable sound of discrete electronics - having previously stuck to a philosophy of '100% analogue' - the opportunities offered by modern digital algorithms and communications for professional recording studio workflows was simply too exciting to ignore.

Now with the Gravity Mix & Master, Tierra Audio combines the strengths of both worlds for the first time in its history - squeezing each of them to the extreme! - and guided by two basic pillars: quality and flexibility.

Future-proof electronics.

 

After dozens of prototypes, the A+D (analogue+Digital) electronics were designed and tested more than 100 times(!) using the best components on the market, until Tierra were certain they had incorporated the most suitable technology and creative solutions, even where others had tried different solutions before.

The result is a fully analogue audio path that meets the exquisite quality standards of the most premium segment of the market - together with a powerful and efficient digital architecture, which opens a new window for collaboration between manufacturer and end users, allowing both parties to incorporate new ideas and solutions thanks to Tierra's open source TA Community API and private feedback channels.

 

Tons of added utility all in a 1U chassis.

Smart workflows. Obsession for precision.

 

From day one, Tierra Audio tried to place themselves in the shoes of the music producer, mix engineer or mastering engineer with the Gravity Mix & Master.

Consulting with professionals from Madrid's recording studios (and beyond), the team sought to understand exactly what producers and engineers require for a modern hybrid workflow, with a sense that there was still plenty of room for improvement.

As TIERRA Audio's Co-Founder Javier Pascual says, "It's only once you've mastered the technology that you truly understand how to apply it, in a way that is genuinely useful to the end user and - most importantly - encourages and facilitates their goals!"

Tierra Audio's Presets and Stage Templates introduce an innovative approach to automation, designed to significantly enhance your daily workflow, and promising substantial time and effort savings for users of the TA Gravity M&M.

Following the principles of open configuration formats and communication standards, Tierra Audio's open-source TA Community API is designed to help demistify a range of historically complex functions used in the Pro Audio sector, allowing users to customise control of the Gravity to their own needs, and encouraging users to share their presets and modifications with others online.

At the same time, Tierra Audio have developed and implemented a number of their own technologies into the Gravity Mix & Master, ensuring the impeccable demands and precision of Mastering Engineers are met right out of the box:

TA Multi-Resolution allows you to choose in real time, and with a single touch, the step size for the most important parameters, from as little as 0.2 dB for Threshold/MakeUp, and from 1% for Blend when mixing and mastering (to much larger steps perfect for live performances).

TA Smart Ambience for automatically calibrating the device, so that the elementary electronic components (resistors, capacitors, transistors, diodes and VCAs) always work under stable and homogeneous physical conditions between different sessions, always synchronized with your DAW.

TA Pulse continuously and transparently monitors that the device's sonic, electronics and electrical performance remains as optimal as if it had just left the factory and, in the event of any deviation, automatically initiates a pro-active warranty claim process that anticipates a potential future incident, reducing studio downtime to zero due to technical problems.
