Being one of the most responsive software available today, Audacity has the capability of recording from directly from your laptop's microphone, line input or even via a USB/firewire. A position it has earned itself over the years as a result of the multi-featured, easy-to-use interface that it spots.

For my MacBook Pro at least - not a cheap machine by any stretch - a 2-or-more input external device, like the Focusrite Scarlett 2i2, seems required to record in stereo.02 of 04 Audacity Audio Editor & RecorderĪudacity by the Audacity Developers Inc sits on the top echelon of audio recorders. That said, Apples’ engineers should be ashamed of themselves if they decided to save a few pennies by tying one mic into what’s advertised via their System Information app as a “stereo” offering. Serious audio users often buy external audio interfaces because they provide higher quality A/D and D/A conversion. What Pro Tools recorded also looks like dual mono:Īnd zooming in via Audacity confirms this: The Morale of This Story Pro Tools was also configured to send the “stereo” mics (Mcrphn1 and 2) to two different channels (Otpt1 and 2): I ran an equivalent test in Pro Tools, which accessed built-in I/O via: Note that the Audacity screen-shots above indicate that CoreAudio was used to access the computer’s built-in audio, so recording was presumably via the “stereo” built-in mic (mics?). Zooming in a bit continues to support dual mono:Īnd - notice the switch to impulse values - becomes even more obvious when zooming in further: Note that left-side taps are louder than the right side taps, which correlates with what is shown in Step 34 of the link cited earlier. When recording via Audacity, the result sure looks like dual mono: In the tests that follow, I record the “stereo” built-in mic by first tapping on my computer’s left speaker grill, and then its right, using similar pressure for each tap. Pro Tools, which contains other features that far exceed Audacity - for instance, automatic adjusting for device latency when over-dubbing - makes per-sample viewing more cumbersome, as adjacent samples are always displayed by the lines connecting them. One nice feature of Audacity is that, if you zoom finely enough, it switches from connecting adjacent samples via lines to showing their individual impulse values, and this makes it is easier to verify when a recorded stereo signal contains identical information in both channels (i.e. I am uncertain which clock source (or both) Pro Tools actually uses when selecting this aggregate via its Setup > Playback Engine menu. An explanation for why the two don’t necessarily share the same clock source might be provided here.

Note that when displaying this aggregate, for input, I selected the input mic’s clock source, and chose the output clock’s source when displaying output. Similarly, the Pro Tools Aggregate I/O (which Pro Tools needs to access built-in I/O) uses the same devices: Note that, while output provides 2 channels of volume control, input only provides one.

That said, here’s what my Audio MIDI Setup Utility has to say about the Built-in output: I’ve also read that MacBook Pro internal mics are an array that do record in stereo (can’t find those links now). Others have reported (see step 34) that the computer’s physical microphone lies around the center of the left speaker grill. This situation confuses me because the system reports two audio channels for both input and output:įinally my frustration got the better of me in this post, I explore this conundrum.

I’ve had a MacBook Pro (Retina, 15-inch, Mid 2015) running macOS Sierra v.10.12.6 for years, and I’ve repeatedly noticed that Audacity and ProTools do not record two independent tracks when using its built-in microphone.
