Set up the Audacity sound interface and get ready to record

And is that Audacity has become on its own merits one of the best free editors and recorders on the market. With it we can record audio through a microphone or a mixer, as well as use a mixer or record the playback that sounds through the PC speakers. In order to get the most out of the application we are going to show you some settings to configure the sound interface. To do this, we only have to access its «Preferences» menu that we find within the «Edit» tab or by directly pressing the keyboard shortcut «Ctrl + P».

Configure channel output in Audacity

From the Preference menu we can configure channel outputs, as well as the server that we are going to use, all in its “Devices” section. Here we can select the audio output channels that may well be Mono or Stereo. As we will surely know, with the Mono channel we will have a sound signal, while in Stereo we will have two signals themselves, so that it can transmit different information. It should be noted that it does not influence the sound quality only in its transmission, so we must choose the one we are most interested in working with, either with one output or two.

Choose the server to work

Also from the “Devices” section, it is convenient to choose the server that we are going to use, for which we will have three options. One of them is MME, which is the most compatible recording interface, but it is also the oldest. Another option is Windows DirectSound what is the most recommended as it offers good results and is compatible with a large number of devices. Finally, the mode Windows WASAPI, is specially designed to record PC audio with lower latency and better results, although on the contrary it has fewer compatible devices.

Select the sampling frequency

From the «Quality» section, we will be able to select sample rate and the bit depth for recordings. By default, a default sampling frequency of 44100 Hz is selected, although we can select different values, so we can choose the sampling frequency that our sound card allows us, which normally ranges from 8000 to 334000 Hz. We will choose the one that best suits our work. For example, if we were making an audio for Blu-Ray we would select 96000 Hz sample rate.

Set the bit depth when recording with Audacity

We can also select the default sample format, that is, the bit depth. Here, the more bit depth counts, the greater the number of vertical divisions that can be obtained from the sample, which affects the audio quality. In general, the greater the amount of audio, the less noise we will have in the signal and we will have a greater dynamic range to record. This we can leave in 24 bitas the 32-bit option is done by software, which can cause tampering in recordings. In addition, we can configure the program in the event that we do recordings with different sampling format. Although it is always recommended to record with the quality to which we are going to export the final result, in this way we avoid quality losses.
