Basic requirements for recording a podcast
To create a podcast the following are necessary:
- A relatively modern computer with speakers, and internet connection.
- A microphone. Some computers have a in-built mic, but a more expensive external mic will create better quality audio recordings.
- Digital recording software (such as Audacity) to create the audio files. However, there are software packages (such as ProfCast on the Apple Mac) designed specifically for audio and video podcasting that may now be more suitable.
Audio podcasts (usually MP3s) are easier to create and the filesize is more manageable for upload and download, but nevertheless it is now simple to create video podcasts using podcasting software. In addition to the requirements above, video needs:
- A video camera. This can be a simple USB webcam or a more expensive digital video camera connected to the computer.
It is possible to record audio podcasts into portable media players (such as an iPod with a mic attachment) but the quality is not necessarily high and this requires the extra step of transferring the audio file from the media player to the computer.

Recording hardware options
There are many means of recording audio and video for podcasts, with varying levels of expensive and complexity.
By far the simplest method is to record directly into a computer using its own internal mic, but the audio quality will not be exceptional and the mic is likely to pick up background noise (from the computer's fan, for example). Using an external microphone produces a cleaner signal.
Regardless of the means by which podcasts are recorded, to publish them it is usually required to transfer the recording from the recording device to a computer with access to the internet. In general, the fewer steps required to generate the final podcast file on a computer, the better.
Other options for recording include:
- An iPhone or iPad using the built-in microphone can generate reasonable results. For higher quality an external microphone can be connected using Lightning, USB-C or Bluetooth depending on the phone/tablet model.
- A portable recorder, such as a Marantz PMD 661 Solid State MP3 Recorder, can be a relatively inexpensive and yet high quality option for audio recording. Many of these portable recorders make use of SD cards and other modern storage cards.
- Expensive external USB (not analogue) microphones (such as a Samson CO1U USB mic) can be plugged directly into a computer and provide very high quality audio recordings. Additional attachments to isolate background noise can increase the quality.
- Digital video cameras can be used for audio and video input for use in podcasts, often connected via USB.
