Anleitung Zusammenfassung
• When using the recording as an audio track for a video, we recommend setting the frequency to 48 kHz. • The sampling frequency of a recorded song cannot be changed on the R-09HR. • When the sampling frequency is either 88.2 kHz or 96.0 kHz, MP3 cannot be selected with the Recording mode. 34 Recording Recording Recording mode MP3 64 kbps MP3 96 kbps MP3 128 kbps MP3 160 kbps MP3 192 kbps MP3 224 kbps MP3 320 kbps WAV 16 bit WAV 24 bit ¦ WAV versus MP3 WAV songs (*.WAV) store all sound information without compression; MP3 songs (*.MP3) store songs using compression. Consequently, WAV songs have a better sound quality recording than MP3 songs. On the other hand, MP3 reduce data volume by removing frequencies that are hard for the human ear to hear. When recording with MP3, the song size is smaller than the WAV setting recording, and a longer recording can be made. ¦ bps and bit The higher the value, the better the sound quality. The MP3 bps is the bit rate unit (bits per second). The bit rate indicates data transfer rates in number of bits sent per second. The WAV bit is used to represent the size of a sample. The sample size indicates the amount of precision used in capturing subtle changes in the sound. Larger sampling size values allow for more details of the sound to be expressed, and result in sound that is smoother and more natural. • Higher bps and bit values result in larger song sizes and shorter recording times. • Software such as Windows Media Player cannot play back 24 bit WAV files. MP3 can be selected only when the sampling frequency is 44.1 kHz or 48 kHz. Recording Recording The approximate recording time for memory cards is shown below.

The times may change depending on the card specifications. Furthermore, the actual recording time is shorter when there are multiple files. 37 Recording fig.mic-LR.eps_80 The internal microphone is a stereo microphone. The sound picked up by the microphone on the right side of the R-09HR is recorded on the right channel (R), while the sound that the microphone on the left captures is recorded on the left channel (L). • To prevent feedback when recording with a microphone, do not connect speakers. • If a microphone or other device is connected to the [LINE IN Jack] or [MIC Input Jack], the [Internal Mic] cannot be used. When using the [Internal MIC], do not connect anything to the [MIC Jack] or [LINE IN Jack]. Set monitoring on when recording to monitor the sound through headphones while recording. . “Setting whether to monitor sound while recording” (p. 100) fig.power-onoff-e.eps_80 1.
