Did LAME lowpass filters change? 2015-03-12 07:40:38 I recently came back to an encoding project I sat aside for a year or so. I've been encoding hundreds of hours of .wav files (digitized from VHS h-fi recordings of FM radio broadcasts) to mp3s using the LAME V6 preset. Since building a new computer system and getting the latest versions of Exact Audio Copy and LAME, one tiny aspect of encoding seems different. I could have sworn the default lowpass filter at V6 was around 15.5KHz, which is perfect for FM radio recordings, but now as I use LAME, I see the lowpass band at V6 is around 17kHz. I don't recall specifying a lowpass of 15.5 last year with my old computer setup. Seems like I recall being happy that V6 preset fit FM radio so perfectly.Anyway, I can add the -lowpass 15.5 term to my LAME command line, but I'm just wondering if I'm nuts or if the default lowpass for V6 was different before.
