 Posted: Tue May 20, 2008 9:10 pm Post subject: [SOLVED]convert wav to mp3 without hisses |
 |
|
I am trying to convert a wav file which is too big into mp3. The wav was recorded with | Code: | | rec -c 2 -r 48000 test.wav |
I recorded it with -c 2 to get a better quality. The output was too big and I want to burn it on 1 cd. I used audacity to convert to mp3, but hisses were introduced. There were some hisses in the wav as well but at an acceptable level. Converting them to mp3 increased the noise, and it really annoys. Is there some trick to reduce it? Or at least to bring it back to the level that in the wav.

I have not had any hissing problems; but i have found that audacity files are much larger the from command line. this script is set to convert all wav files in current directory.
| Code: | #!/bin/bash
#
# wav2mp3
#
for i in *.wav; do
#out=$(ls $i | sed -e 's/.wav//g')
#out=$(echo $i | sed -e 's/.wav$//')
#lame -h -b 192 "$i" "$out.mp3"
/usr/bin/lame -h -b 192 "$i" "${i%.wav}.mp3"
done |
and of course you can adjust to your needs:
http://linux.die.net/man/1/lame
i added done to the script 5-21-08 i got cut off on original post sorry

there are only 9 line check and make sure of accuracy.
you can also run for a single file
| Code: |
/usr/bin/lame -h -b 192 filein.wav fileout.mp3 |

I noticed it's nine lines. I can't understand why it complained about line 10. I would like to use this script for more files in the future.
Since I had now only one file to convert, I ran from command line and it worked perfectly. No hisses. I am amazed. |

I deleted the lines that are commented and spaces in the rest of the lines . It still sees one more line than it should. I will type everything again.
Thanks a lot.  |

Thanks. 
I am ashamed as well. I guess I was tired as well and didn't notice. |

It would be better to use VBR, for example: lame -V 2 --vbr-new
