Record Zoom, Skype and Telegram calls

Who can use Audio Hijack

First of all, to all those who started working from home. All these Zoom- and Skype-flyers can now be recorded and then calmly listen to the missing details.

For example, almost all important information flies out of my head an hour after the call. But, audio recordings help me to re-listen to important points and make a text Summary. And if something does not agree, then re-write with the interlocutor and clarify specific points. If this is a conversation with a customer or further actions and work on a project are being discussed, then there is definitely nowhere without a record.

How Audio Hijack works

The Audio Hijack interface displays the process of recording any audio as a pipeline of blocks. This approach is more difficult than the usual “record” button, but it gives more control over what is happening.

For example, in a conveyor chain, you can: insert filters that remove hum and noise; add effects; see the RMS scale to control the level of your microphone and the interlocutor.

To add a new block to the recording system, you just need to drag it to the appropriate place. In this case, I added the Dehum blog to remove the background hum.

If this functionality seems redundant to you, then the developers of Audio Hijack have the Piezo application, which simply records the sound of your chosen application and your system microphone. But, all this without additional control on your part.

How Audio Hijack works is session based. Simply put, these are ordinary projects within an application. You need to create a session once for each type of recording, and then it can already be reused.

Sessions work like projects. Each session has its own settings: where and with what quality the recording is made, where the files are saved, which microphone is used, etc.

For example, you can sort Zoom conversation sessions by interlocutor. Thus, if you are discussing a project with the developers, the entry will be named according to the given template and will go to the correct folder. If you’re talking to marketers, then the recording will end up in your marketing conversations folder, which is great.

Also, the program has twelve ready-made templates for all occasions: from recording the sound of any application to recording a podcast with several present and remote guests.

How to record a conversation in Skype, Zoom and Telegram

According to the developers, call recording is the most common use case for Audio Hijack. Therefore, the application already has special templates for recording them.

After creating a session, you just need to select the application from which you will record the call.

To add a new block to the recording system, you just need to drag it to the appropriate place. In this case, I added a Dehum blog to remove the background hum.

Let’s see how this chain works using the example of a call recording from Zoom.

By default, AH splits your voice and the other person’s voice into separate tracks. That is, when you listen to the recording, you will sound in one ear, and the interlocutor in the other. A track with just your voice can come in handy when editing a podcast.

If you do not like this effect and you want all voices to sound on both tracks, then the channel separation option can be disabled in the settings by clicking on the sound source icon.

By default, Audio Hijack uses the microphone selected in the recording application, and also splits your voice and the voice of the other person into two separate tracks

Also note that the program will record your voice with a microphone, which is set as a system microphone or is selected in the sound source program. If desired, the source can be specified manually by dragging a block into the pipeline.

Next we have a block Peak / RMS… It shows the levels of your microphone and the voice of the interlocutor, in the left and right columns, respectively. If this scale goes into the red zone, then you need to lower the sensitivity of the microphone. If it hardly moves, then on the contrary – on the recording you will be barely audible and the sensitivity needs to be increased.

After the RMS meter block comes the block Recordwhich writes audio to a new file. In its settings, you can set the file name template for this session, as well as the folder where the recordings will go.

If this is a session for work calls for a project, then the template can be configured so that it adds the project name to the file and saves it to the desired folder.

You can also add tags, cover, description, etc. to the file.

Block Chanels merges tracks during conversations so that your voice and the voices of the other people sound in both ears. And then this sound is output through the Output Device block to the desired headphones.

Additional filters

Before recording audio to a file, you can place some additional filters. They will correct various audio flaws and make further listening more enjoyable. It is useful if you have a low-quality microphone that captures extraneous noises.

for example Dehum removes background hum caused by interference from other equipment or wires. Declick – smoothes or removes random clicking and clicking sounds that may appear when you press the mouse and keyboard buttons.

Reliability of records

Before recording real calls, I recommend doing a few test cases. At first, I got a little confused with the microphones and couldn’t record my voice. But, if you use ready-made templates, then everything should work flawlessly.

Also, the developers claim that they have a reinforced concrete system for protecting the file from force majeure situations at the time of recording: program departure, computer restart, etc. Whatever happens, the file must remain readable and interrupt only at the moment of failure.

I tried to hard reset my MacBook while recording a call. And I confirm – the file really remained intact and readable.

What equipment do I use

Now I use a microphone to record conversations Blue yeti… While he just stands on the table on foam rubber, which smooths out the noise transmitted from the table.

Before that I used a microphone Rode podcastermounted on a tripod. This setup completely suited me, but it remained in another country, so now I had to switch to Blue yeti

As for the headphones, everything is simple, it’s AirPods Pro. For them, I bought comfortable black ear pads, which you can read about in the AirPods Pro review. In the future, I want to change them to closed wired headphones, but have not yet decided on the model.

Where to download Audio Hijack

The program has a demo version, the only limitation of which is call recording for no more than 10 minutes. After ten minutes, noise will be added to the recording that cannot be removed. But, if you restart the program, you can record another ten minutes and so on ad infinitum.

The full version costs $ 59. If you need a simpler option, then again I will remind you about Piezo from the same developers.

As a supplement, I recommend reading the article about the Sound Control application, which allows you to adjust the volume of individual applications, and put things in order in audio sources.
