John, we would appreciate your input about whether these new
implementation of atempo is superior or equal to the existing one with
regard to your needs.
I tested scaletempo (with default settings) and it is definitely worse
than atempo for small scaling factors like 25/24.
Have you tried other scaling factors?
How you done testing?
Simple hearing tests. I hear audible artifacts (a kind of audio
stuttering) with scaletempo. Here are some files where it is noticable:
fate-suite/delphine-cin/LOGO-partial.CIN
fate-suite/real/spygames-2MB.rmvb
fate-suite/wmapro/Beethovens_9th-1_small.wma
fate-suite/dts/dts.ts
The last one is noticable even with 2x scaling.
Regards,
Marton
