| Notes | Original audio shared by Ricola on Jan. 25, 2007 Ricola Notes: Another broken Reel to Reel tape which I repaired and just finished to transfer on CD. Editing Notes: -Original audio had a significant phase error with the left channel leading the right by on average 17 samples, with some variation -Automatic phase corrections to handle the variations -Levels started off reasonably balanced, but the right channel became significantly weaker as the recording progressed -Constant amplification of 3 dB to the left channel, and automatic, varying level adjustments to the right channel to balance with the left -Original audio was running considerably slow - almost a whole tone, 11.5%, but at least it was consistently off -Because it was running so slow, the more appropriate new sampling frequency is actually 48 kHz instead of 44.1 kHz in order to preserve more of the information that Ricola captured in the original transfer (not that there's actually very useful detail in those high frequencies here - it's just tape hiss > 10 kHz) -So instead of resampling (speed adjusting) by 11.5% to correspond to a 44.1 kHz sampling frequency, the resampling factor was only 1.115*44.1/48 = 1.0244 or 2.44% -All edits done in MATLAB -ledwhofloyd (Ross), Jan. 2023 |
