I have recorded several mono files at 11 KHz from cassettes. They are about 45 minutes of speech each. After dehissing their size in the hard disk is about 50MB each. When trying to record them onto CD with Adaptec's Easy CD Creator, the WAV file size increases to about 300MB and only one of them fits a CD as two would render an OVERFLOW message due to more than 650MB of CD capacity. Why this file increase size? How can it be avoided?

Re: File Size increases when writing to CD. Why?
In order to record on a Audio CD, the file must first be converted to a 44.1kHz, Stereo file. This is the only format that is supported by Red Book Audio CD's. What Adaptec's software does, is first to convert your 11kHz mono files to 44.1kHz, Stereo files, then creates the CD format image from that. So 45 minutes of speech takes up 45min of the 65minutes that is normally available on a CDR. You cannot avoid this if you want to record in the Audio format. If you make a CDRom out of it, and leave the file as a wav file it will stay the same size. Of course you cannot play this on a normal CD player.

Thank you for your thorough and prompt reply, Rick !
If you know any car/home cdplayer that may play the 50MB files, I will appreciate your recommendation...
