Compared to a WAV file, the file size of an MP3 is much smaller, because the content is compressed. This is convenient for example to place recorded content on a web site or send it by e-mail. 3. Move the jog dial up/down to bring the cursor to "MP3 ENCODE". Then press the jog dial. The MP3 ENCODE screen for selecting the source WAV file appears. 4. NOTE Depending on the type of card and the recording format, the conversion process may take about as long as the recording time of the source file. The unit should therefore be powered from the AC adapter during the conversion. Sufficient free space will also be needed on the card. Move the jog dial up/down to select the WAV file to convert. Then press the jog dial. A screen for specifying the bit rate (amount of information per second of the MP3 file) and the file name appears. 1. At the stereo mode top screen, press the center of the [MENU] key. The main menu which gives access to various H4 settings appears. 5. To change the bit rate setting, move the jog dial up/down to bring the cursor to "BIT". Then press the jog dial. 2. Move the jog dial up/down to bring the cursor to "FILE". Then press the jog dial. The bit rate setting can now be changed. Move the jog dial up/down to select one of the following settings, and then press the jog dial. Available bit rate settings The FILE menu for selecting various operations for recorded files appears. 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256, 320 (kbps), VBR The higher the bit rate setting, the better the sound quality. The setting "VBR" stands for "Variable Bit Rate". With this setting, the bit rate adapts to the amount of information that is to be H4 Version 2.0 Supplemental Manual 5 H4 Version 2.0 Supplemental Manual encoded. This method makes it possible to achieve fairly small file sizes without excessive degradation of sound quality. Using the auto recording function (stereo mode only) The auto record function makes it possible to have the H4 start and stop recording automatically, according to the input signal level. When the level exceeds a certain threshold, recording starts, and when it remains below the threshold for a given length of time, recording stops. This is convenient to record only spoken comments at a meeting or interview or similar. To use the auto recording function, proceed as follows. 6. To change the file name, move the jog dial up/down to bring the cursor to "NAME". Then press the jog dial. The cursor disappears and a character is underlined. This indicates that the character can be changed. Specify the name, using the same procedure as described on page 47 of the H4 Operation Manual. 7.
