TrainYourEars EQ Edition is an ear training software for Mac and PC designed to help you understand equalisers and frequencies like never before.

It speeds up your learning process exposing you to hundreds of random equalizations you have to guess. If you are wrong, it will let you know “how wrong”, and it will let you hear both your guess and the correct answer.
In no time you will develop a frequency memory which will allow you to connect the sound you imagine in your head with the parameters you need to dial, quickly and easily than ever.

It has a brand new training method. Instead of guessing, you have to make corrections while you hear the result.
The person who suggested this method to us in the first place was Bob Katz, a renowned mastering guru. We tested it, we loved it, so here it is for all you to enjoy!
Besides it has a new, modern and clean interface, a new assisted training screen, a new exercise designer, it supports other languages, and many other features.
The ability to connect what is in your mind with the appropriate parameters you have to dial to get that sound is not an easy task. The steps involved should be:
Sometimes people get lost in the translation step and start turning knobs without confidence. The more you work, the better you understand what those knobs really do, but it is a slow process.
People excel in this matter after many years, because they have learned experimenting with lots of different processes applied to lots of different sources. The purpose of this training is to open your ears to what each frequency sounds like and reduce the amount of time needed to acquire this knowledge.
In 15 minutes you can guess or correct 100 random equalisations, so training every day for a few weeks is equivalent to accumulating the experience of many years.
First, you load the music you want to train with:

Then, you choose an exercise or design a new one:

And finally, train your ears with one of these two methods!

Multicast Upgrade Tool: A Comprehensive Solution for Efficient Network Upgrades
While the story above captures the "feeling" of the process, in the real world, a Multicast Upgrade Tool is a utility often used by network administrators and hardware technicians to:
We have experienced zero issues with the tool's reliability. It has consistently performed as expected, and our upgrades have been completed without any hiccups. The tool's robust error handling and logging capabilities have also helped us identify and troubleshoot any issues that have arisen during the upgrade process. multicast upgrade tool
The company’s CEO had given the order: “Upgrade by midnight, or the shareholders’ call fails.” A firmware bug was corrupting multicast video feeds—stock tickers, boardroom broadcasts, critical data. Patching each switch manually would take three days. Elias had three hours.
The tool is designed for scenarios where standard web-based updates fail or when a device is "bricked" and cannot reach its administrative interface. Key features include: The company’s CEO had given the order: “Upgrade
Why multicast?
Phase 5: Rollback If >5% of clients fail, the tool automatically triggers a rollback stream for the previous firmware version. 5% of clients fail
The Multicast Upgrade Tool represents a fundamental shift from connection-oriented to content-oriented distribution. It is the engineer's answer to the square-cube law of network upgrades: as the number of devices grows linearly, the bandwidth and time required grow only logarithmically or remain constant. While it demands a multicast-capable network fabric and careful handling of loss recovery, its efficiency in high-scale environments (data centers, ISP headends, industrial control systems) is unmatched. As edge computing and IoT deployments scale into the millions, the multicast upgrade tool will transition from a niche utility into a core pillar of resilient, bandwidth-aware infrastructure automation. The future of mass upgrade lies not in more powerful servers, but in smarter, multicast-native delivery.

READ MORE TESTIMONIALSFinal price was 89€, but the 49€ launch offer was such a success that we sold twice as many as we expected.
After a lot of thought we decided to keep this reduced price forever :)
Thanks to all the people who has supported this project so far and made this possible!
