These are first, the quality of the psychoacoustic model used for data reduction and second, the bitrate of the mp3pro file. The size of the loss depends very much on two factors. Nevertheless, a certain loss of acoustic information is unavoidable. Most test listeners can hardly (or not at all) distinguish between the sound from mp3pro files that have been stored with a sufficiently high bitrate from the original files. When encoding, psychoacoustic models are used to remove "inaudible" acoustic elements from the audio file. Encoding audio files as mp3pro files is always bound up with losses. Click on the 'Enable mp3pro' button box if you want to encode files in the mp3pro format. Click on the 'Settings' button to display the parameters for encoding. The 'Source file info' field is for your information and gives details about the quality of the file to be encoded. Click on the 'Browse' button in the 'Target file' area to indicate the directory where you would like the file to be saved. Click on the dropdown button in the 'Output file format' and highlight 'mp3pro (*.mp3)'. Highlight the audio file(s) that you would like to encode and click on the 'Open' button.Ĥ You do not need to highlight the selected file(s) because all the files displayed will be encoded. Change to the directory containing the files to be encoded. (1) Encoding a Wave file Select the 'Encode Files' command from the 'Extras' menu and click on the 'Add' button. This permits unlimited encoding (into either the mp3pro or the MP3 format). With Nero, you can convert up to 30 files into the MP3 or mp3pro format and then obtain the mp3pro encoder plug-in from our Website. The second method permits the tracks on an audio CD to be encoded. The first method allows you to encode existing audio files (*.wav) that are located on your hard disk or a CD-ROM (but not on an audio CD). Both formats share the 'mp3' file extension How you can make your own mp3pro files with Nero Using Nero, you can create mp3pro format compressed files (*.mp3) in two different ways. An mp3pro file is about half the size of an MP3 file but the quality is the same. Nero automatically decodes the MP3/mp3PRO files before burning and as a result you will receive an audio CD that can be played on any CD player.ģ The mp3pro encoder You can encode audio files in the MP3 or mp3pro format with the mp3pro encoder plug-in. Click on the 'Burn' button to begin the writing procedure. Check the following steps, paying particular attention to the writing speed and the method of writing. However, the 'Burn' tab (index card) is now on top. The 'Burn Compilation' dialog box will now open this is the same as what you see when you are making a new compilation. It will show how many minutes of music or how much space is still left on the CD.Ģ When you are ready, click on the 'Burns the current compilation' button or select the 'Burn compilation' command in the 'Recorder' menu to start the burn dialog. Note the blue bar in the lower part of the window. Change to the directory containing the MP3/mp3PRO files, highlight the files you want and drag them into the compilation window. Now you only need to use 'drag and drop' to pull the MP3/mp3PRO files from the file browser into the compilation window together with your chosen audio CD selection. Activate the 'Write CD TEXT on CD' check box if your recorder supports this function. The 'Audio CD' index card will be on top. Select as disc type 'CD' and highlight the 'Audio CD' icon on the left and the appropriate tab ('index card') will open. 1 MP3/mp3PRO plug-in How you can make an audio CD from mp3 or mp3pro files.1 The mp3pro encoder.2 How you can make your own mp3pro files with Nero.3 How you can make your own MP3 files with Nero.12 How you can make an audio CD from mp3 or mp3pro files Launch 'Nero' and the dialog for creating a new disk will appear.
