Interview with music teacher, Rob Lee, about using drop.io in his classroom

For the assignment where I had to record a conversation with another person, I chose to interview a good friend of mine, Rob Lee, about how he uses drop.io in his high school music classes.

Interview Feedback

good job

I liked your questions

I liked how you summarized the answers.

I also liked that you did it in 5 minutes

I liked how you signaled the end of the interview. I'm going to take a page from your book when I do my next interview.

I liked that you were up front that he was a friend and that he was helping you out.

what I would have liked to know is how you create an account and the link to drop.io
I looked it up in google

I hope you will let me interview you along with a couple of webcast interns to share our experiences in participating in the webcast academy course.

yeah for you. you did good

Sample Rate

Hi Thomas,
 Enjoyed the interview - useful info about drop.io and audio was clear. You'll notice that there's now audio flash player - that's because the audio was recorded at a 16kHz sample rate.

For the flash player to work, it needs to be 22 or 44 kHz. Not sure if that's a setting that can be changed in Pamela and it's nearly impossible to convert afterward without re-recording the audio. Pamela and other conversation recording programs are the most painless way to record conversations, although if you're interested in streaming the live conversations, they won't get the job done.  For that, you'll need the more painful 'Advanced Recording Methods

Recording in Pamela

Not sure what happened there. Here is what I did:

- Recorded Skype call using Pamela as a .wav
- Put the file through the Levelator program, which create an output wav file
- Used Audacity 1.3 beta to do a quick edit and exported it as an mp3 file.

I had Audacity set to the suggested 44khz sample rate & 64kbs bitrate. I checked both Skype and Pamela and I could not find anywhere to set this for recording. Wondering if Levelator is the culprit?

Who's the culprit?

I could be wrong, but I suspect Pamela. My experience has been that sample rate is set in the initial recording and it's pretty hard to alter regardless of other programs the audio passes through. Is there any place for sample rate settings in Pamela?

I've been very satisfied using Skype Call Recorder ( http://voipcallrecording.com/ ) Records as an mp3 at 128kbs / 44kHz sample rate. That provides a pretty high quality source audio that can be edited in Audacity and exported as a 64kbs file.

Pamela and Audio quality

Jeff,
Thanks for the feedback. I tried looking in Pamela for audio settings but could not find anything. I'll give Skype Call Recorder a try.

I was thinking that if I wanted to keep the quality of audio high that I had to record in an uncompressed format like .wav. I read that if you edit an mp3 file in Audacity that audio quality becomes a problem because you are compressing it again once you save and export as an mp3. Not sure about this so i though I would ask.

Source audio quality

It is a good idea to aim for the best quality possible for source audio. That's one advantage of using Audacity - you get totally raw, uncompressed audio to edit.

However, when recording telephony calls (as opposed to hifi recordings of a symphony), things like mic quality and background noise are probably more significant than whether one's working from an uncompressed audio source or not. Another reason I like skype call recorder is that it allows for a 128kbs mono mp3 recording. Since we publish at 64kbs, it gives us a higher quality source audio to edit. I like to record in mono because there usually isn't any stereo component to a telephony call and recording a single 128kbs track essentially provides the same quality as recording 256kbs stereo tracks.
