The two filtered signals are summed (15) to create a first monophonic signal (16).
Similar steps and hardware are utilized by the monophonic version.
A CELP encoding part (103) performs a CELP encoding of the monophonic signal (M).
The present invention provides a monophonic or stereo audio coding method.
The monophonic layer may comprise one of the rotated signals and the gain profile.
A monaural / stereo selector switch (50) may be used to select between stereo and monaural audio throughput.
Multi-channel audio signals are coded into a monaural audio signal and information allowing to recover the multi-channel audio signal from the monaural audio signal and the information.
In this stereo signal generating apparatus (90), an FT part (901) converts a monaural signal (M't) of time domain to a monaural signal (M') of frequency domain.
There is provided an audio encoding device capable of generating an appropriate monaural signal from a stereo signal while suppressing the lowering of encoding efficiency of the monaural signal.
A stereophonic or monaural adapter is connected to an FM automobile radio via the cigarette lighter of the vehicle.
This mono-aurol audio equipment to receive isolator effect.
The combined parameter values are then used for synthesizing the mono audio signal.
A method of generating a monaural signal (S) comprising a combination of at least two input audio channels (L, R) is disclosed.
To this goal the delay between a computed monaural signal and one of the input signals is used.
The music isolator requires a stereo signal input to function, but has a mono-aural output.
The sounds are stored monaurally and are converted to directional sounds using known techniques.
Alternatively, the receiver or user himself may select the mono transmission channel he wishes to receive.
The invention relates to a method of synthesizing a mono audio signal based on an available encoded multichannel audio signal.
This circuit arrangement first forms a combined monaural signal (at 10) and a differential signal (at 12) from the two stereo signals (Lin, Rin).
