Question- How do you record your slidecast audio?
May 16, 01:03 am PST
We are compiling a bunch of suggestions (quick tips) about Slidecasting in order to smoothen the process of creating an audio file and synching it to the slide deck.
I have a question to our users who are creating slidecasts- if your audio is a recorded talk or commentary, how are you doing it? I mean, are you recording it on your computer using the windows voice recorder, or using audacity? If you are recording it live during the event, do you use a portable voice recorder (i.e. Olympus & Sony have these), or maybe a mobile phone, a camera, or some other instrument thereof. How much does it cost to procure such a recorder, where can you buy it… those kind of questions. Please let us know in the comments section for this post… we are going to compile this and put it on slideshare.
Any other tips, tricks, suggestions about slidecasting, recording audio, synching it etc are welcome.. we are all ears … we want to improve the slidecasting experience.

Some amateur tips
For slidecasts created on the computer, say like a audio-video tutorial or a photo slideshow with music, I could record my sound using a mic and then edit (if necessary) using Audacity or Sound Forge.
For recording live presentations, probably record using a mobile phone voice recorder (but do not use the phone’s default app since that generally imposes a limit on recording times). Use a third party app, which are commonly available for Symbian and Windows Mobile based phones. If the mic picks up too much noise in the background, I think it’s a good idea to cleanup the sound later on and then use that.
Does anyone know of a good place to upload files for free in such a way that the mp3 is accessible directly from the URL?

Gaurav,
The internet archives are a great place… its free, it supports creative commons and readily gives the mp3 url. Its easy to use as well

Audacity is a free audio editor and file convertor (to mp3 format) and rather easy to use so if you were recording on a computer directly or editing audio — that’s as good as any.
But your format has to be mp3 or ogg.
But I record on a mini disc recorder and record into Audacity again using an iMic for my podcasts(rather than the MiniDisc software). I get a nicer sound with more room. But in effect you could record on anything away from the computer and re-record it to Audacity (or another recorder via line in or mic)
We’ve offered some DIY here:

including a list of preferred free upload sites.
My estimation is that for a simple slideshare/slidecast an account on Wikispaces is fine
http://altmedianetwork.wikispaces.com/
so long as you keep your file under 10MB. That’s about 20-30 minutes of audio at 22 kHZ and 32 kbps. You don’t need anything fancy for lecture voice.
There are other free sites we list –. but within that range you can’t beat Wikispaces I reckon as so many of the others have let me down.
If you have a mp3 file , say from your mp3 player you can edit it with a range of mp3 file splitter software

As for recorder cost — it depends on what you want to use. The key question is whether the rig will take a microphone input and what sort of mic may be required. It’s a question of sound quality…and preference. I like Mini Discs for a few reasons but esp because they offer automatic “gain” — sound/volume modulation.
but I’m a bit alone in that regard as the new flash players are taking over.
