When the bell sound is later analysed, the frequency of the reference tone is checked at the same time. If there is a discrepancy, work out the ratio of […]

Recording and analysis

The pages linked below give practical tips on recording bells for the purposes of tonal analysis (including taking recordings from Youtube, and how to do the tonal analysis with Wavanal. The detail given in previous version of these pages (written almost 20 years ago) on recording formats and recording devices has been completely re-written and […]
