Solve : Audacity lame? |
|
Answer» 1. I have Audacity to record my own spoken material. To convert it to MP3 I NEEDED Lame. I have installed it, following the step-by-step program. However, when I want to convert a recording to MP3 I get the pop up Could Not Open MP3 Encoding Library. I have repeated this quite a few times, always - not surprisingly - with the same result. Any good advice? 1. I have Audacity to record my own spoken material. To convert it to MP3 I needed Lame. I have installed it, following the step-by-step program.

Any good advice?are you using windows, linnux or mac? for #1 try going http://forum.audacityteam.org/viewtopic.php?f=16&t=9976&9976 for #2 they would have to be compressed or they would be vary vary largeThanks for that, Smeezekitty I checked your advice for my #1 question and found to my great relief that it was not my ignorance that created this problem, but that there were quite a few inquiries for the same problem. I still find it quite cumbersome, but at least I can now do wav and mp3. - BTW I use Windows. #2: daft question: compressed is the same as zip, is it? Do the buyers of my material have to have unzip / de-compress software? SEE, I want to make it as easy as I possibly can for them. Thanks again.

Not daft question, smeezekitty is right; For sound files, mp3 is a compressed format; wav is not; 30 minutes mp3 stereo at 192 kbps is around 40 MB; 30 mins wav is around 300 MB. wav is a totally pointless format for web distribution. With spoken material you could use a much lower bitrate than 192 kbps and maybe mono and get even smaller mp3 files. No point in compressing mp3 files in a zip archive, as not much size REDUCTION is possible if files are already compressed. Thank you Salmon Trout; you took a weight off my shoulders! You might be able to answer my second question: I will put a downloadable / printable book for sale on the internet. It's about 1Mb PDF. Zip or not? Bearing in mind that I want to make it as easy as I possible can for the buyer. Thanks in advance.Using maximum zip compression in WinRAR, I did a test for you (you could have done this yourself!) Code: [Select]26/07/2008 19:56 1,968,333 mg_barcelona.pdf 07/09/2009 10:08 1,937,667 mg_barcelona.zip So not much. PDF files are like mp3, wmv, mpeg, and jpg files; already compressed, so that no compression algorithm can find any big savings to make. I even downloaded a "free" "pdf compression" program and the output file was 100% of the size of the original. So the answer is, don't bother; PDF format is already optimized for web distribution, and using zip will only INTRODUCE an un-needed step that your customers will have to take, making the process less easy, for no good reason. Once again thank you so much Salmon Trout; that's another weight off my shoulders - still a few more to go. |
