I am happy to discover the free Audacity DAW uses ISO standard scientific notation or analyzing pitches. I discovered this because I am using Audacity to try to figure out if the drummer in one of our songs is correct about the bass player being a bit out of tune. I think maybe he is but I want a second opinion from Audacity. To get a solid framework from which to work I tuned up my guitar using the NCH Perfect pitch tuner which uses the ISO standard and determined that Audacity reports the same ISO standard pitch for the note (D3). Do do this in Audacity I recorded my D string then highlight the recorded note, go into Audacity (Effect, Change pitch) and get the value it is saying.
