The current methodology to correct azimuth on quarter inch audio tape based upon a combination of spectral tools and listening abilities has led in the last 25 years to common practices how to digitize tapes with wrongly adjusted azimuth. In a recent field test with senior archive audio engineers and young students, a test was done to compare different approaches how to adjust azimuth – based upon ears, spectral tools, and completely new approaches. The test results of traditional and new methodologies will be presented, which might put a new light and a question in the way how collections have been digitised in the past.
