Optimizing your recording is an essential part of the music crafting process. If you have a recording, whether from a professional studio or zoom recorder, it is best to ensure that its sonic potential is maximized for your listeners. Fine-tuning a recording for an ideal listening experience that suits today's music consumption culture, where music is streamed online and delivered via people's earbuds, is a crucial part of being a professional music maker. Whether you are polishing up an album/EP or preparing for a compelling YouTube video, Toshi is here to help reach a higher standard for your uncompromising passion.
