Software substitute for Nakamichi T-100 Audio Analyzer

[Cobra2]

 

 

 

NAK T-100 software simulator

 

NAK T-100 is a lightweight and all-inclusive audio analyzer for inspecting analog audio devices on computer. It is capable of performing 7+ conventional audio measurements in a single setup without swapping a stack of physical instruments. This makes it an agile tool to quickly check whether a given audio device performs to its specifications. Or during a service/repair/modify project, this is a less overkill yet more cost-effective tool for conducting general audio measurements on desk top. Some of the key functions are specifically optimized for tuning analog tape players/recorders.

 

The app features modern DSP core with traditional analog skin. It adopts the "Skeuomorphism" design philosophy to offer era-specific operational experience in working with analog audio devices. However, the underlaying engine works purely from digital domain after all, which does not have to follow the analog measurement principles and yield strict identical readings. Typical tolerances across typologies of test instruments should be expected.
