Mac audio input frequency 320 kbps#

For example, an 8 Kbps MP3 recording tops out at 24 kHz, while a 320 Kbps MP3 recording will offer custom sample rate options between 32 kHz and 48 kHz.Buying Audio Interfaces at Sweetwater is Better! You can customize the sample rate of MP3 recordings, but do be aware that the bit rate of the recording dictates the available sample rates. The MP3 and AAC formats will record at a maximum of 48 kHz, automatically adjusting the sample rate based on the sample rate of your session as well as the bit rate of your recording file. When you select a specific sample rate for your recording, the Recorder block will resample audio as needed. You can set a custom sample rate by clicking the Advanced Recording Options section, which will reveal additional sample rate options. However, the MP3, AIFF, and WAV recording formats offer custom sample rate settings, if desired. Sample rates for recordingsД«y default, the Recorder block follows the sample rate setting of your session automatically. When you have the device configured as desired, restart your Audio Hijack session.ДЄlternatively, you can change the sample rate from its Automatic setting in the Info tab of the session's sidebar. You can adjust the format of your devices with MacOS's Audio MIDI Setup utility, found in the Utilities folder of the main Applications folder. If you start a session and find that its sample rate is not what you expect, you'll want to check the sample rates of your connected devices. The sample rate of the session will then be set to the highest rate found. If an Input Device source is present in the session, Audio Hijack will also check the sample rate of the selected input device, in addition to the sample rates of all output devices attached to the Mac. The session will then run at the highest rate found among the connected devices. If an Application block is present in the session, Audio Hijack will check the sample rate of all of your Mac's output devices. If that device is using a sample rate higher than 44.1 kHz, the session will run at that higher sample rate. If a System Audio block is connected to an Output Device block, Audio Hijack will check the sample rate of the selected output device. To determine what sample rate to use, Audio Hijack checks all sources and outputs at the time the session is started, then applies the following rules:ДЄudio Hijack will always run at a minimum sample rate of 44.1 kHz. How Audio Hijack sets the session's sample rate automatically When necessary, Audio Hijack will automatically resample source audio to match the session's rate.

While the session is running, this rate will not change, even if the sample rates of any sources or outputs change. The sample rate for an active session is displayed as part of the panel displaying information at the bottom of the session window:Д®ach time a session is activated, the sample rate which will be used is automatically determined, and locked in. When using Audio Hijack, audio is captured at a fixed sample rate which is set each time a session runs. A sample rate represents how frequently audio data is recorded for playback through your speakers: common sample rates are 44.1 kHz (44,100 samples per second) and 48 kHz (48,000 samples per second).
