One of the tools used for yesterday's ET630 class summary was PodOmatic, a platform for users to create and publish audio and video podcasts. The educational value of podcasts is immense. Course lectures can be had for free (look for example at Khan Academy and MIT Open Courseware). Although I do not teach foreign language in school, I see the value in using podcasts in foreign language classes: learning vocabulary, reciting dialogues, conducting interviews, etc. (I did some of this in the summer of 2013 when I took Korean language classes at Sogang University in Seoul, Korea.)
You start by signing up for a free account on the PodOmatic website. PRO members are allowed more bandwidth and they can get more storage. There isn't a separate app for mobile devices or tablets, per se, but there are apps for Android and iOS that allows you to listen or watch podcasts on PodOmatic. Once you register, you will eventually have your own URL for your own podcasts (here is mine).
(Note that once you post your first PodOmatic podcast, you get a free 30-day PRO membership, which is nice.)
According to this help page, you can use the PodOmatic Audio Recorder to capture audio, as long as you have a microphone (I haven't used this feature yet). You can also use a separate program to record and edit audio, which is what I did. I would recommend Audacity, which is FREE. Once you create your podcast, you upload it to the website. One nice touch is the ability to upload a picture as well, a useful feature. Go to my PodOmatic page and see the podcasts I have created thus far.
