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? |

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? |

I thought the current version of Audacity did sample rate
conversions. |
