I published my first podcast, called PodLeaders back in around 2006 and ran it for two years. I have set up and published a several more podcasts since then, including my most recent one, the Digital Supply Chain podcast which I set up in June of last year.
The recent Coronavirus pandemic has brought a halt to my travels and this allowed me to focus more on the podcast, and in doing so I learned a LOT about how to improve the quality of your podcast. The improvement in quality has coincided with a big upswing in listenership, which is nice. Some of this increase may be to do with the uptick in quality, but it is also likely to be that the content is more topical (several Coronavirus impact on supply chain podcasts), and because the frequency of publication has gone up.
So here is my new and (vastly) improved podcast process, in case it helps anyone else with their podcast (or podcast aspirations!).
Step 1 in my podcast is to schedule the guest interview. This is quite straightforward if the guest is an SAP colleague as I can see their availability on their calendars, and vice versa, but for folks outside the organisation this can be a lot of back and forward, so I set up a Calendly account. Calendly allows people to see and book the available slots on my calendar, and so saves a lot of the to'ing and fro'ing that is otherwise required to find a mutually agreeable time.
Step 2. Once the recording time is confirmed (or sometimes a prep call, followed by the recording), I set up the call on the podcast recording platform Squadcast. Squadcast, like Zencastr records in lossless WAV format for better quality audio, but unlike Zencastr, Squadcast uploads the recorded file live to the cloud for safe storage, as the podcast is happening, and it also has a video interface, so you can see the person you are talking to. I can't stress enough how much better this makes conversation flow. The video is not recorded (and guests have an option not to turn on their cameras, if they're not comfortable, or they're still in their pyjamas!). Squadcast do say they will add an option to record video later this year, so if this is something you need, they will be adding it.
Once the interview has concluded, I download the WAV files from Squadcast, and I run them quickly through the Noise Reduction and Normalisation sound effects in Audacity (an open source audio editing program). The Noise Reduction in Audacity is particularly easy to use, and can quickly get rid of any annoying static, or hissing sounds that may have been picked up.
Having exported the cleaned-up files from Audacity, I drop them into Hindenburg Journalist Pro - this is an application which is specifically created for the editing of podcasts. This is the only software I'm aware of which is specifically created for podcast production. Journalist Pro's user interface does take a little getting used to, but they have great video tutorials online to help get you up-to-speed quickly, and they have a 30 Day free trial, so you can try before you buy. The auto-levelling, the voice profiles, the granular volume controls, are some some of the many reasons this program is a podcaster's best friend. For reference, before Journalist Pro, I used to use GarageBand, and that is not bad, but because it is a program designed for music editing, there were quirks and work-arounds you had to do all the time when working on podcasts. On the other hand, GarageBand if free if you own a Mac, so that's something to take into consideration too.
Once the podcast production is completed in Journalist Pro, you can export it directly to your podcast host site. In my case, my podcast host is called Buzzsprout. I have used other podcast hosting sites like Libsyn, and Podbean, but to my mind Buzzsprout is the best of them. And I say this not specifically for any technical reasons, but rather because they go out of their way to make the podcast publication process painless. Not just do they have a nice simple interface for podcast publication, but they also have a great Youtube channel with loads of fantastic tips and tricks to help you set up, or improve your podcast, a cool podcast of their own (duh!), and a useful newsletter. It was via their newsletter that I learned of Journalist Pro, for example. However, when I've finished with the production in Journalist Pro, I don't publish the audio directly to Buzzsprout, instead I export it as a WAV file to my computer.
I export the WAV file to my disk because I want to improve it a little more. So now, I upload the file to Auphonic. Auphonic is a magic site which just improves your files audio. From the screenshot above you can see the before waveform at the bottom, and the after waveform at the top - the audio levels have been levelled! Not just that, the audio post Auphonic just sounds better. Now it is ready to be published!
So, I upload the file to Buzzsprout, and also most times to Trint as well. What is Trint? Trint is a site that does transcription of audio files using AI. This means you get the transcription back in minutes, rather than the days it can take when you are relying on humans to do the transcription. Trint also has a free trial, so if you're interested in trying it out, you have nothing to lose - really, it is not one of those free trials where they take your credit card details and make it hard for you to back out. As transcription goes, the output is quite good. It is not perfect, obviously and will need some work to clean it up, but it is fast, and it has an excellent interface for that inevitable clean-up. Then, I post the transcriptions on my TomRaftery.com blog, along with the Buzzsprout player so anyone who is interested can listen to the podcast, and read along the text as well, see here for an example.
Ok, that's it. Those are my seven steps to better podcasts. For now. I'm always learning, so I may do a follow-up as I learn more.
