My school has some lectures that were videotaped available on our website. I don't really want the video part of it, just the audio. So I am just recording them into mp3 format (cause I don't know any other way). The thing is I am not sure what the audio quality is. I would like to adjust the bitrate setting of the mp3 recorder to roughly the same quality to save file size but not compromise quality. Can anyone tell me what the quality might be or tell me how to find out?
The first lecture is 54m32sec, it says bitrate 289 Kbps, video size 328x216 Audio codec: 48 kbps, 44 kHz, mono 1-pass CBR, 115.21 MB.
I recorded this lecture at 256 Kbps mp3 and the file is ~100MB. The video has got to be less right? I mean alot of that 115+MB has got to be video data... Is there someway to convert the information I have into a rough audio quality?
