You can make a decent audio test set with a good computer sound card and a plethora of free software.Of course to do this right, good measurement quality sound cards are expensive like in the $1000 range. But you can do OK with basic quality stuff and you can always upgrade later.
Also a PC based system can quite easily do FFT and other advanced math functions where as dedicated equipment for that is very expensive even used.
The biggest problem with PC based gear is the noise inside a typical PC. A better solution is a sound capture / generator device that plugs in via USB. That way the analog circuitry is better isolated from the internal RFI of the PC.
