I’m hoping to find a way to extract dB values in spreadsheet form. Is there a function in audacity to output, say, a .csv file with dB values over time using the PC timestamp?
Backstory: I develop automotive Tier 1 accessory OE exhaust systems and our customers have sound pressure level thresholds that we have been trying to evaluate and design around using Audacity. Currently, we calibrate the microphone and then hunt through a spectrogram track looking for hotspots in what we know to be the sensitive frequency range, using the “Plot Spectrum” tool to ascertain the peak in whatever hotspot regions we identify. If we could log dB levels with respect to time, we could sync the data with OBD2 engine data logs to filter the dB data by load, rpm, throttle position, etc.
If Audacity can’t do this, I’d love to hear about any other tool that can. Regardless, thank you contributing to make Audacity an amazing piece of software.
