Request for mix mastering & track cleaning


why? Solves the problem of not getting the desired "that sound"

There are high barriers to producing professional quality master sound sources. Famous artists use top-notch engineers, expensive vintage equipment, and even the latest plug-ins in every direction to finish their work from a wide range of choices.

DAWs in recent years have abundant high-quality sound sources and presets from the beginning, and somehow it becomes cool, but there are many creators who are worried about not knowing what to do for the next level.

Supporting vocalists and musicians who want to make songs with a high degree of perfection, but "I can't learn the equipment" and "I want to specialize in my specialty", and creators who can't get close to the finished image even if they challenge them To do.

For artists who are looking for works that cannot be satisfied with automatic mastering

Online mastering by LANDR and automatic mastering by iZotope Ozone 8 have improved the automatic analysis power by AI, and anyone can master about 85 points by using them. However, the sound creation made by excellent engineers is constantly refined, and the master sound source is finished to a higher level.

We are not a famous engineer who works on major artists. I was wondering if there would be no human-powered mastering offers, but there are many people who are pleased with the high cost performance and are asked to repeat.

Removes mobile phone radio noise mixed in band performance (with improvement sample)

When recording a performance with a linear PCM recorder, there seems to be a case where the recorded data gets quite terrible noise if the iPhone is nearby. It is not the noise of the environmental sound of the audience seats picked up by the so-called microphone, but the very strong noise that destroys the audio data itself.

We have worked to reduce unpleasant noise that interferes with the recorded performance.
