Title: Noise reduction circuit
Inventor: TAKAHASHI SATOSHI
IPC: H04N5/21
Filed: 1991-08-27
Abstract: PURPOSE:To provide a digital noise reduction circuit in which an S/N is improved, and a zero-cross distortion is reduced. CONSTITUTION:Digital signals are divided into the digital signals corresponding to noise signal components by digital band pass filets 101-105. The digital signals of a level lower than a threshold level are discriminated from those of a level higher than the threshold level by limiters 121-125, and the low level signals are outputted. The signals are mixed by a digital mixer 14. A difference signal obtained by subtracting the low level signal from the original signal is outputted by a digital subtracting circuit 8. The low level signals exceeding the threshold level are discriminated from signals fluctuating within the range of the threshold level by zero-cross distortion removing circuits 221-225. The circuits 221-225 permits the passage of the low level digital signals fluctuating within the range of the threshold level through the digital mixer, and prohibits the passage of the whole or a part of the low level digital signals fluctuating beyond the range of the threshold level through the digital mixer.

Filed: 1995-08-03
Abstract: PROBLEM TO BE SOLVED: To provide the singing voice synthesizing device which enables natural singing by making good use of musical performance data that are generated originally for a musical instrument performance. SOLUTION: Musical performance data are read out in order and when a read event is a key-off event, it is decided whether or not the breathing flag BREATHFLG of text data being vocalized is set to '1' (step S36); when BREATHFLG is set to '1' and a breather is specified, a muting process is performed (step S37). When BREATHFLG is set to '0', on the other hand, the muting process is not performed. Then, the muting process is performed when a next key-on event is generated (steps S30 and S31). Consequently, singing is carried out without a break of a text except a text whose breathing flag is set to '1'.

Abstract: PURPOSE:To minimize a damage due to strong fading, etc., by separating successively a front and rear taps installed at the front and rear of the main tap in accordance with the extent of a coding error ratio. CONSTITUTION:When due to the fading, etc., the synchronizing step-out signal output of a demodulator and a coding error signal output occur, an action mode change-over device 110 is started, a coding error ratio is received from a decoding device side, and when the error ratio is small, first, to separate the terminal away from the main tap, change-over switches 105P and 108P are operated, and respective contacts are opened. In accordance with the extent of the coding error ratio, the mixer is not successively controlled stepwise. By controlling in such a manner, a multi pass fading is recovered, and then, the automation is returned from the condition closer to the time when the multi pass fading occurs and for that reason, a recovery time can be shortened. Thus, the confusion which occurs when much distortions such as fading exists at the line, is removed and a more stable action can be executed.

Abstract: PURPOSE:To prevent a sound from being ceased owing to vibration of a CD player. CONSTITUTION:A speech signal is written in a memory 16 and an address detecting circuit 12 extracts address information from the output of an amplifying circuit 9 and outputs the address. If a tracking deviation is caused owing to the vibration, etc., an abnormality detection signal is outputted. A speech holding circuit 13 holds the speech signal in response to the abnormality detection signal and an address holding circuit 14 holds the address. A system control circuit 18 instructs a memory control circuit 17 to stop writing to a memory 16, and sends an access indication to an access control circuit 11 to return a playback head 4 to the address held by the address holding circuit 14. When the reproduction is restarted and the speech signal held by the speech holding circuit 13 is outputted from a signal processing circuit 7, a coincidence detecting circuit 15 outputs a coincidence detection signal and sends an indication to the memory control circuit 17 so that the writing to the memory 16 is started.
