I don’t want to click play in QuickTime just yet. Then I need to open the audio file in QuickTime. We’ve done the groundwork to start piping the audio recordings into the otter.ai transcription service, so let’s make it happen.Īfter logging into my otter.ai account, I need to push the red start button in Audio Hijack. Loopback Pass-Thru virtual audio device with optional monitor The Process This would have eliminated the need for adding my speakers to the Audio Hijack session. In Loopback when you create a virtual audio device, like my Pass-Thru device called otter.ai, you can add a Monitor and set it to your speaker of choice. Note that there was another way to allow me to hear QuickTime while I was hijacking it. Audio Hijack with QuickTime input otter ai output plus speaker block Luckily with Audio Hijack, you can have multiple output devices, so I dragged in a second audio output device and pointed it to my internal speakers. I had “hijacked” it and sent it to this virtual device, so it wouldn’t play through to my speakers. With Audio Hijack set up with QuickTime as the input and otter.ai as the output, I could have used this to send audio to otter.ai, but I wouldn’t have been able to hear the audio playing in QuickTime. Since they aren’t physical devices, they can act as either input or output and sometimes both. Pass-Thru devices from Loopback are sort of magical that way. This is going to get a little bit head bendy here because I just told you the output is otter.ai, but in a minute, otter.ai is going to be the input to our application. Then I dragged in an output device and selected the virtual device I created using Loopback called otter.ai. As my input source, I chose an Application block and set it to the application QuickTime. Audio Hijack allows you to drag and drop little blocks on screen to represent input and output devices, and you can add tons of other features in between. Now that I have this virtual audio device, I can use it in Audio Hijack. It’s as though it’s a physical device permanently connected to your Mac. Loopback Pass Thru virtual audio deviceĪs soon as that virtual device is created in Loopback, it is now available all throughout the operating system, even when Loopback isn’t running. I should mention that there is nothing magical about the name I chose, but I named it otter.ai so I could easily identify it by its intended use in my list of audio input devices. By default, all virtual devices in Loopback include a Pass-Thru block, and that’s all I needed. In Loopback, I simply added a New Virtual Device, and named it otter.ai. The idea is that any audio you send to that Pass-Thru device as the output, will then be able to go directly into one of these web-based tools. You can do some crazy advanced stuff with Loopback, but one of the simplest, and frankly most valuable things you can create is called a Pass-Thru device. Loopback allows you to create virtual audio devices. Here’s how the two apps combine to solve the problem at hand. I used two of their tools to accomplish my goal: Loopback and Audio Hijack. We need a way to pipe audio into this service as though it was a microphone.Įnter my heroes, the people at Rogue Amoeba. But in the problem we’re solving today, we want to play the audio recordings using something like QuickTime, and use that application as the input to otter.ai. For example, if you go to Skype or Zoom or a Google Hangout (or otter.ai) they expect you to select your physical microphone as the input source. The paid-for plan isn’t expensive at $10 month-to-month or $100/year and I’ve paid it before but I wondered if I had the tools to get the job done without it.Īny tool that accepts audio input will be looking for a physical hardware device in the form of a microphone. That’s pretty sweet but it only allows 3 imports per month on the free plan. The free version of otter.ai allows you to import audio files and have them transcribed automatically. A few people sent in written transcripts of their submissions but the vast majority were audio-only.īack in January I told you about a cool web-based transcription service called otter.ai and I wondered if I could use it to transcribe the audio recordings. You know that I’m committed to giving people the content the way they want it, so I really wanted to be able to provide the messages in these audio recordings to those who prefer to (or must) get their content by reading. Last week’s episode of the NosillaCast was pure joy for me because of the wonderful audio recordings sent in by so many NosillaCastaways.
