A podcast is a form of audio broadcasting found on the internet. Podcasts can be used on any device having a music player installed. They are like blogs that you come across. Just like you subscribe to blogs, you can also subscribe to podcasts and get updates from time to time. An advantage to using podcasts is that the audio you will play can also be saved or downloaded on your device so that you can listen to it later whenever you like it.
One of the most renowned applications which offer podcast facility is iTunes. Once you have subscribed to a channel, it will notify you if there is a new audio from that subscription. As we know, we can download an audio file. Similarly, we can also upload a podcasting audio for public to listen to.
Recording your audio may be natural but letting the world listen to it can be a bit confusing. In earlier days, it used to be impossible to let the world know what you have successfully made. It is known that a podcast has two parts, namely the audio file and the XML file. The XML file is responsible for telling the subscribers about your new audio.
The podcast is like blogging and other businesses that acquire internet based self-publishing. Podcasts contain RSS (an acronym for ‘Simple Syndication’ or ‘Rich Site Summary’) which informs your subscriber of your new audio updates.
The user must use RSS to get updates on their favorite blogs. You are going to create the XML file first. Your case must be smaller than 512Kb otherwise some users will not be able to take advantage of your audio. After this you must use some validator service (example: www.castfeedvalidator.com) or your podcast will not be uploaded. After validating your audio file, you can upload it to your website. In case, you do not have any internet site; you can upload it to other places.
First, you must check your website storage plans. Some sites do not allow large files to be stored. You are authorized to upload your podcasting audio on your site, but it might face problems of storage and bandwidth. Bandwidth is a problem faced when your audio becomes popular more than usual. To avoid such problems, podcasters prefer using external podcast hosting service. To upload a file, your audio must have a URL which would be submitted to the hosting website. You must enter the full URL when saving the audio file for your podcast. The URL must be registered in the enclosure field of the RSS document and guide field as well. After uploading the XML file, your file will start to update. To make sure that it is working correctly, you can subscribe to your feed and check whether you get any updates or not.
You can use podcast hosting services to avoid blogging on your website due to storage and bandwidth problems. Following is a list of podcast hosting services:
1. Soundcloud: This forum is mostly used by podcasters. To add your podcast audio, you must have a Soundcloud Pro account.
