| Summary | 0000051: sound quality in emailed sound files could be improved | ||||||||
| Description |
Capisuite converts .la to .wav files before sending them to the user. This conversion is done with sox and produces a 8 bit per sample wav file. Converting 8 bit a-law (nonlinear) to 8 bit wav (linear) is a loss of quality (13 bit linar needed if i remember right) Wav file should be 16bit. This can be achieved by telling sox to use 16 bit output, option -w before outfile (word size). |
||||||||
| Additional Information |
Add -w in cs_helpers.py ret = os.spawnlp(os.P_WAIT,"sox","sox",attachment,"-w ",basename+"wav") |

Yes, definitely right suggestion. I will change it as soon as bug 52 is solved. |
