Customer Feedback & Improvement Examples

It was a difficult request for voice adjustment, but I was able to respond flexibly by trying various methods . If you have such a case, please feel free to contact us. Thank you very much. (Video production company)

Thank you for adjusting the applause and other parts. I was struggling because I couldn't hear the words at all with the original sound source, so it was really helpful to be able to make adjustments.  

(Participant of a certain academic society)

It's amazing. Room noise and various other noises can be removed. The reverberating sound also disappears. It sounds like you're talking to the microphone in front of you. I also got the ringtone for my cell phone . My voice is a little distorted in the part that is covered with my voice. However, there is no extra sound. I was able to suppress the other sounds, including the talking voice.
