Piezo 1.9.10 Mac

Grabbing audio from a specific application on a Mac used to mean wrestling with virtual drivers or complex routing. Piezo strips that down to two clicks: pick a source, hit record. Developed by Rogue Amoeba, the app treats every running program and connected microphone as a straightforward recording target, no extra configuration required.

Here is one realistic task from start to finish: recording a video call for a colleague who missed the meeting. Open Piezo and a source list appears immediately, showing every audio-producing app currently active. Select the video-call application as the source and click the red record button. As of version 1.9.10, Piezo can save each participant on a separate channel when the source supplies multi-track audio, which makes later editing far simpler. When the call ends, stop the recording and give the file a name. The uncompressed recording lands on the desktop, ready to share or drop into an editor. The same flow works for internet radio, streaming performances, or voice memos from a USB microphone. Piezo keeps the interface focused on that single job, so the steps never multiply.

A podcaster’s afternoon

Imagine a freelance podcaster who books remote interviews through Riverside and Zoom but also records quick solo segments with a Blue Yeti on the kitchen table. Before Piezo she kept a cheat sheet of input settings for each app, because switching from the Yeti to a VoIP guest meant hunting through three different audio preference panes. Now she opens Piezo, sees the Yeti and the browser-based call listed side by side, and picks whichever source matches the moment. A single click starts the capture. She names the clip after the guest and adds a comment like “second try, no cat interruptions.” The file saves as a standard AAC and lands on the desktop with the name she gave it, so she never confuses raw tracks. After recording she drags the clip into Logic Pro for cleanup. The whole routing step that used to eat ten minutes is gone.

Check these details before you download

Will Piezo grab system audio from any app I run?

Yes, with a practical catch: Piezo sees whatever application is producing audio at that moment. If the app is silent or hasn’t started playback, it won’t appear in the source list. Start the audio first, then open or refresh Piezo’s list, and the source shows up. Browsers, media players, VoIP tools, and games all register the same way.

Recording your mic and an app at the same time

Piezo records one source per session. If you want to capture your own microphone alongside application audio, you can run two instances of Piezo simultaneously—one set to the USB mic, one set to the target app—or record the app audio in Piezo while monitoring yourself through a separate recording tool. Rogue Amoeba’s own Audio Hijack handles multi-source setups natively, but Piezo stays deliberately single-source for speed.

What file format does it produce?

Piezo saves recordings in AAC or MP3 by default, depending on the quality setting you choose. The uncompressed option preserves full PCM audio when you need lossless material for editing. Every file lands with the name and comment you entered, so file management requires no detective work later.

Why your audio source stays hidden at first

Source not appearing in the list. This catches new users most often. Piezo polls for active audio streams, which means a dormant app with no sound output stays hidden. Launch the app, play something—even a second of audio—and the source appears. On macOS 14.4 and later, also check that Piezo has been granted Microphone access in System Settings > Privacy & Security; the prompt sometimes gets dismissed accidentally during the first launch.

Recorded file is silent. Usually a routing mismatch. Confirm the intended source is selected and actively producing sound at a volume the system can hear. If the source is a browser tab, make sure that tab isn’t muted at the operating-system level—macOS can mute individual tabs independently of the browser’s own volume control. For VoIP apps, verify the call is using the expected output device and that the other party is actually speaking.

Gatekeeper blocks the install. The piezo mac full version download arrives as a disk image. If macOS flags it, mount the image, right-click the installer, and choose Open. A Terminal-assisted bypass is also documented, but the right-click method works for most setups running macOS 15 and later.

Multi-channel recording doesn’t split tracks. Separate channels only happen when the source application supplies distinct audio streams. A VoIP call recorded through a browser that mixes all participants into a single output will produce one track. Dedicated recording platforms that expose individual participant feeds before mixing deliver the split Piezo can save.

Version 1.9.10 brings Piezo forward to macOS 27 and drops the launch warning that appeared on that system. No other changes were noted in this release, issued August 14, 2026.
