It is depending on wich equipment you have. lets say you have an earphones wich cost 10 dollar. then the bitrate don't have any impact att all. but if you have one for 200 then of corse you hear the diference if it's 128 or 256 kbps. I can hear that and describe it like there is something missing in the lower bitrate. if it higher then the sound is fol. or how to describe it???

128 isn't anywhere near FM quality. I'm not stating that as my opinion. It is agreed by those who are knowledgeable on this subject and who are audiofiles or work with audio [professionally. 128kbps is often used when inferior small speakers are being used for listening or when small wlakman like headphones are used. When listened to with good reproduction equipment, 128kbps files do not have a full bodied sound. they sound smaller than is desirable. It is debated whether the human ear can hear the difference between 256kbps and CD quality and 320kbps and CD quality. It is also debated whether the human ear can hear the difference between 256 and 320kbps when compared with each other. But it is not CD quality. Even 320kbps is not CD quality. Whether the human ear can hear the difference or not, technically no mp3 file is CD quality because Mp3 is a compressed format. I'm talking about stereo files, not files recorded in the monaural format. In the monaural format, you get roughly the equivalent sound at half the bit rate when compared with a stereo or joint stereo file. thus, a 64kbps monaural format file would sound approximately equivalent to a 128kbps stereo format file. 16kbps may sound alright to you. I don't recall seeing anyone else ever saying it is acceptable or even sounds ok. I understood that you intended to send the file by e-mail. I responded by saying that these days, As I said in my original message, sending files as attachments that are at all large is anachronistic. People send files using Drop Box, Sky Drive, or other file sharing methods that are at all large. Also, I should add that I saw a message from a list member earlier today discussing variable bit rate settings. I'm not agreeing or disagreeing with that message. I haven't looked into variable bit rates. I'm discussing what I've read about and I've read almost exclusively about fixed bit rate quality. Gene ----- original Message ----- From: William Brandes Sent: Monday, February 17, 2014 12:03 PM To: audacity4blind@xxxxxxxxxxxxxthe operative term was that i wanted to send by email. actually the 16 bit rate sounds ok. although, i normally would use 32 or 64 bit rate. 128 considered fm quality. 256 cd quality. william On 2/17/14, Gene <gsasner@xxxxxxxxx> wrote:the goal, to allow an audio file to be sent buy e-mail, is years, perhaps a decade, behind the times. With Drop Box and other ways of very easily sharing larger files available, trying to cram a recording into an e-mail attachment size limit is really anachronistic. 16kpbs sounds just plain terrible. I would not go below 32kbps for voice. That's 32kbps monaural. I would not go below 128kbps for music, that's 128kbps stereo or joint stereo.

If you record something like podcast, you should export it at mp3 variable bitrate usign the folowing step Ctrl+shift+e open the export dialog Alt+o option dialog. From the mp3 export setup choose variable. From the mp3 export setup quality choose from 4 to 6. The lower number the smaller file size. I usually choose 5. See this link for more info http://theaudacitytopodcast.com/06 If you have iTunes installed, I recommend you to export your recorded file to wave, and use iTunes to convert it to mp3. See this link to know how to do it: http://www.spreaker.com/user/dangmanhcuong/create-mp3-file-using-itunes-and-jaws remember: if your recorded file doesn't require anything related to stereo, you should convert it to mono and convert to mp3 using iTunes. The file size would be reduce a half.
