This does not interrupt audio played by pulseaudio, it just records it as if it were also an input device. If you select this "Monitor" as your audio input device, that application will no longer record audio from microphones, but will capture any audio sent to your sound card. One of those options will read, "Monitor of ". You can click this button and change it to any audio device you wish such as a different microphone. Watch the videos below to see just how easy it is to get up and running.

You'll notice that there's a button next to each application that displays the device it is listening on for audio input. The Audio Loop-back feature is surprisingly easy to use due to the free custom dedicated software mixers that come with both the iD interfaces. You can set it lower if you want, but the volume at which audio is played by your system is the volume at which it will be recorded. Make sure your software volume output (the volume level in pavucontrol, not the volume knob on your external speakers) is set to 100%, but not more than that in order to avoid distortion. In the capture settings for your application, enter the audio capture device as "pulse".Īfter you've verified that your recording software is indeed listening for input using pulseaudio and it appears in the recording tab of pavucontrol, we can now change where it listens for input. If your application is actively recording, but does not appear in the recording tab of pavucontrol, then it is not using pulseaudio for this purpose. Remember the application has to be actively recording audio input, so if you're using something like gtk-recordmydesktop, it must be actively capturing your screen to appear here. In the "Recording" tab, you will see a list of all applications currently listening for audio input. The tab we're interested in is the "Recording" tab. You'll notice at the top of the window several tabs. PDF, 1.6 Mb, Revisión: C, Archivo publicado: nov 12, 2008.

Low Power Stereo Audio Codec for Portable Audio/Telephony datasheet. Once pavucontrol is installed you can use it to change a variety of options regarding your sound, more-so than the default sound manager in most desktop environments. TLV320AIC32: CODEC estéreo de baja potencia con 6 entradas, 6 salidas, amplificador HP / Speaker y efectos 3D.

One method you can use to accomplish this is to ?install and use the software package pavucontrol, which is available in the Debian repositories, by executing: # apt-get install pavucontrol This could be useful for screen recording sessions where you want to capture the audio as it is produced instead of just setting an external microphone next to your speaker. There are 14 gain settings available: ×1, ×2, ×3, ×4, ×6, ×8, ×12, ×16, ×24, ×32, ×48, ×64, ×96, and ×128.FEATURES Dual, simultaneous sampling, 14-bit, 2-channel ADC True differential analog inputs Programmable gain stage: ×1, ×2, ×3, ×4, ×6, ×8, ×12, ×16, ×24, ×32, ×48, ×64, ×96, ×128 Throughput rate per ADC 1 MSPS for AD7264 500 kSPS for AD7264-5 Analog input impedance: >1 GΩ Wide input bandwidth −3 dB bandwidth: 1.7 MHz at gain = 2 4 on-chip comparators SNR: 78 dB typical at gain = 2, 71 dB typical at gain = 32 Device offset calibration System gain calibration On-chip reference: 2.Pulseaudio provides us with the means to easily create an audio loopback device that allows us to record sounds produced by our system as if they were being redirected into the microphone. Each ADC is preceded by a true differential analog input with a PGA.

Two complete ADC functions allow simultaneous sampling and conversion of two channels. The AD7264 is a dual, 14-bit, high speed, low power, successive approximation ADC that operates from a single 5 V power supply and features throughput rates of up to 1 MSPS per on-chip ADC (500 kSPS for the AD7264-5).
