There is the good quality piano recording, except the <100Hz noise:
There is my recording:
The recording have a list of problems:
- 20k noise;
- 2.5k-3k noise;
- 1-1k noise;
- <100 noise;
- small signal/noise contrast in silent zone;
- 50-60 low freq. impulses;
- thick (blurry) piano sounds;
I looking the way to illuminate this problems without post-production process. Unfortunately for me, the post production wipes the silent piano sounds and makes the sound more like synthesizer, then grand piano.
I will be happy to hear any recommendations to improve the hardware with short explanation how each element of new equipment will help me.
Current equipment are Marantz PMD660 + Alesis MultyMix4USB + pair of Behringer C-4
