Tempo rate survey results

How accurately can Walking Player and similar apps' automatic tempo analysis feature measure tempo?、I checked the accuracy rate。

(Songs used in the survey)

Kana Nishino's album、96 songs from singles were measured.。

(Survey app)

'WP':Walking Player v1.01
AS:AudioStep v1.01
'TM':Tempo Magic Pro v3.0
'BB':BODiBEAT GPS run&Walk v1.1.5

(For the survey results)

  • AudioStep、The BPM value is displayed to the third decimal place.、Rounded off and expressed as an integer value。
  • Items with “x” in the measurement result column、The app says "unmeasurable"。

(Correct method)

Compare the automatic measurement results of each app with the manual measurement results.、If the difference from the manual measurement result was within ±1, it was considered correct.。Also、If the difference in the result of multiple adjustment was within ±1, it was also considered correct.。
(Example)Automatic measurement results:50、Manual measurement results:101in the case of、50Comparing ×2=100 with the manual measurement results, it was determined to be the correct answer.。

(Rate Roundup)

App name Correct answer rate
Walking Player v1.01 94%
AudioStep v1.01 41%
Tempo Magic Pro v3.0 56%
BODiBEAT GPS run&Walk v1.1.5 81%

(Study on)

  • All three apps other than Walking Player have a certain number of results that are "unmeasurable".、Walking Player、On the analysis algorithm、Never become unmeasurable。What is Walking Player and the other 3 apps?、I suspect that the way tempo is measured is fundamentally different.。
  • BODiBEAT is、Except for the unmeasurable、There are 3 cases with an error of ±2 that gave incorrect values.、There are only two errors larger than that, so、Excellent for the results。however、There are 12 cases that cannot be measured.、I lowered my accuracy rate by that amount.。
  • AudioStep、Tempo Magic Pro is、The accuracy rate is lower than expected。Half needs to be measured manually。
  • Kana Nishino's album、There is a 1 minute prologue/epilogue song at the beginning and end of the album.、There is also a narration-like story within it.、Those songs seem difficult to analyze。Of the 6 things Walking Player got wrong、4This is the prologue song/epilogue song.。vice versa、I think it can be said that it is excellent that there are only 2 errors in a normal song.。
