More iPod Touch MityMic Audio Samples
Many thanks for Graham Scharf of the Tumblon Podcast for his comment asking how the TouchMic.com MityMic microphone sounds when it is placed in the middle of the table, for example when recording an interview around a table without passing the iPhone or Touch back and forward to each person speaking. Great question because the two spoken audio samples that I recorded in my iPod Touch MityMic Review and Audio Samples post were recorded with the mic close to the person speaking. (For more information on the MityMic and how it works with the iPhones or iPod Touch as well as additional audio samples refer to my previous post iPod Touch MityMic Review and Audio Samples)
I have recorded and included a couple more samples in response to Graham’s question, this time with the people speaking further from the mic. As per last time, the MityMic audio samples were recorded using the MityMic microphone, my iPod Touch 2nd Generation, and the Voxie Pro audio recording application. I edited the files using Audacity and did amplify the sound a little and then converted the files into .mp3 format. To maintain the quality of the recordings I used Voxie Pro set to the highest quality setting (CD Quality 44kHz) and the files were converted into .mp3 format at 128 kbits/s bit rate. Note that Voxie Pro set on the highest quality setting may not be feasible for longer interviews.
Sample 4: Livingstone Family lunch (59 sec, 930KB)
In the theme of Graham’s podcasts, which are about children and parenting, this sample features my five year old daughter who dominates any conversation and clearly projects her voice better than her parents. The Touch and MityMic were in the middle of the table and we were having lunch around the table.

Sample 5: Brendon talking a various distances (42 sec, 660KB)
Again with the MityMic in the middle of the table I stood beside the table and at a couple of distances back from the table.

Full disclosure: TouchMic.com provided the MityMic microphone for the purpose of recording the audio samples in this and the previous post. I have not paid for this microphone. Brendon

Hi Graham. Thank you for your latest comment and apologies for not getting back to you sooner on your question relating to Voxie Pro. I quite like VoxiePro and I note that it is also recommended by TouchMic.com. I haven’t used iTalk so much, so it may be okay too. You may want to check out ‘HT Professional Recorder’. I haven’t tried it, so I couldn’t directly recommend it, but the writeup in the apps store states “this is the recorder to get if you care how things sound when recorded at a distance. Signal processing algorithms capture conversations throughout a room, recording both near and distant voices clearly”. It also has the ability to set a gain sensitivity, so that you can amplify at source rather than edit the volume in Audacity. It could be interesting to trial ‘HT Professional Recorder’ – maybe the focus of a future blog entry.
Hi Brendon,
This is very helpful! But I will definitely be doing recording in locations with background noise – eg outside with traffic, at a kids playground, in a cafe.
Could you do a few recordings in those type of locations?
Thanks heaps!

Hi again
also how long does the battery last for long recordings? eg lectures, plays, etc
is there a way it can stay charged while recording?
Hi Olivia
As it turns out someone else had also asked for how the MityMic fared in environments of background noise. So I took some recordings today before I saw your comments. I have created a new post with these samples tonight at http://www.unexpectedidea.com/ipod-mitymic-background-noise. I hope these samples are useful. As I note in the post I think the MityMic does a good job at filtering out more distant background noise, so should work well in outside / playground / cafe recording.
If you are fully charged when you start recording I think you should be fine for 2 hours plus with battery. Bigger issue will be file size. For longer recordings I think you will need to select a lower record quality in whatever recording app you use so the file size is manageable.
Thanks for this post, Brenden! I’m impressed with the quality as far as 2+ meters away. If the input is constant at a distance, presumably you can boost it in Audacity (if necessary) to get a reasonable sound output.
(On your advice, I’ve switched over from iTalk to VoxiePro.)
Thanks again!
