[. . . ] Your USB turntable is compatible with any recording software that supports USB Audio devices. We have included Audacity, however you may prefer to use one of a variety of the 3rd party software packages that are also available. audacity is free software , distributed under the General Public License (GPL). More information, as well as open source code, can be found on the included CD or on the web at http://audacity. [. . . ] There are various types of effects which are described further in the software's help section as well as on the web (See Figure 5). (See Figure 6) Please note: It is a good idea to place the needle on the record, while it is stopped, before you begin the recording and press `Play' on the turntable after you begin recording. If you place the needle down while the record is spinning and after you have began recording, there might be audible clicks and pops. These clicks on pops might not allow the Normalize effect to bring the volume of the recording to the level that it should be. We recommend using the beginning or the end of a track where there is no music and only vinyl noise. (See Figure 7) Select Noise Removal from the Effect drop down menu to bring up the Noise Removal window. If you wish to clean up the entire recording use Select All under the Edit Menu. Adjust the amount of audio that you would like to filter by moving the slider in the Noise Removal window. Note: you can preview the audio before removing the noise by clicking on Previe'. Audio levels may vary based on the cartridge (needle), tone arm counter weight, vinyl, and computer set up. Similar to word processing, you may delete unwanted audio by dragging over the section, which will highlight, then pressing Delete. this may include excessive hiss , silence before/after songs , or skips/scratches. You must select the noise profile before you can remove the noise from a track. If you select actual audio for the noise profile, the computer may remove all of your audio. Once the Noise Profile is set, it will save the profile until you restart the application. In other words, the software must learn what the noise profile is only when you first start the software. You do not need to get the noise profile for every recording once it is set up. Using the USB turntable with Audacity software, you are able to quickly record your 33 1/3 speed vinyl into the computer and use the software to adjust the faster speed back to normal playback. For example, you can record 10 minutes of audio in as little as 7 minutes when recording at 45RPM. Saving three minutes isn't a large saving for one record, but if you are recording multiple LPs, you can record 4 hours of music in under 3 hours. You will hear the audio recording at an unusual pitch due to its high speed. Select from 45 to 33 1/3 and your vinyl will be adjusted to the correct speed as shown in Figure 9. [. . . ] For the first time after installing the LAME MP3 Encoder plug-in, you will be asked for the location of the plug-in file. browse to the Lame MP3 Plugin folder you copied the plug-in file to and select the file. After you have recorded the album, open the Edit menu then click Select then click All. Then select the speed that you recorded at (33 or 45), as well as the speed you would like it to be (78).
