Spent some hours today adding new features, first frequency response, pretty straight forward. Will show scale either referenced to input signal or referenced at 1kHz level. |

Also been playing around with the intermodulation distortion feature, this should give a good view of the IMD performance: 0 dB is the level of the two test tones. |

jaxbird, that is awesome. If you keep this up, and release this software I think I will be buying an Analog Discovery and then send some $$$ your way. Please make this a "poor man's AP setup" :) |

Awesome is a good word for your audio analyzer suite. I was perfectly happy with the capabilities of my Analog Discovery, but now I'm really glad that I own one (although my trusty HP334A is looking a little nervous that it could be departing my main test bench soon to free up some much needed space). Also, a quick thought about your IMD feature. If you see some value in this idea, could the amplitude of the two test tones be made independently adjustable so that you could, for example, test a vintage piece of audio gear using the older SMPTE standard (frequencies of 60Hz and 7KHz, mixed in a 4:1 ratio) if that was desired? That could make an interesting way to compare the test results of the various IMD standards by supplying the appropriate test frequencies and amplitude ratios. I tip my hat to you... keep up the excellent work. |
