This value is sufficient for voice recording and playing.With the minimal recommended configuration (Pentium III 500 MHz or equivalent), there is no problem. This value is the minimum recommended sampling rate if the mixing generator is used.Next?ʏ1Use ConditionsC T;H N~Ki?ىUSE CONDITIONSWHSTREAM version 1.3 is a professional non shareware program.Read carefully the product license contract.
