change sample rate - please help a noobie
I use a personal voice recorder (Olympus VN-480PC) to record class
lectures. It has option to record at different quality levels. Well yesterday my class went long and I was running out of memory so I stopped it and changed the quality to a lower one and had enough space to finish the lecture. I imported the files into Audacity and I noticed the sample rate for the 1st part of the lecture was 11025HZ and the 2nd half was 8000Hz. When I cut and paste the audio from the 8000Hz into the 11025Hz and listen the 8000Hz sounds like the chipmunks! I can't figure out how to resample the second half so it sounds right so that I can have 1 audio file and export it to mp3. Any suggestions? -Mike |

What you want to do is upsample the 8 KHz stuff to 11025 KHz sampling before you try to past the two pieces together. This would be very easy in Audition, for example. What software are you using? |

ups.com I am using Audacity. I think you can change sample rates with it, right? Just change one of the files so that both files have the same sample rate. |

You would think so, but I can't figure out how. If anyone is familiar
with the program, let me know. I currently use it because it is cheap (free!) and thus far did everything I needed. Is there a freeware solution that is better? |
