摘要： The present invention provides an audio processing apparatus for automatically controlling gain. The audio processing apparatus includes an audio signal source and a sound reproduction device. The sound reproduction device attaches to the audio signal source, which includes a storage unit for storing a default gain value and a gain index table. The gain index table lists genre types with a genre gain value of each of the genre types. After receiving a play command signal, the audio signal source fetches an audio file to be played, reads a genre type of the audio file from a tag thereof, and processing the audio file to generate audio signals. The audio signal source further reads a genre gain value of the genre type from the gain index table, amplifies the audio signals by the genre gain value, and sends the amplified audio signals to the sound reproduction device to reproduce corresponding sounds.

摘要： A measure system for signal measurement is introduced. The measure system simplifies the effort for a signal measurement in many applications. The application for a signal measurement is, for example, computation of a signal average value. The measure system includes a digital computation circuit together with an analog to digital converter (ADC) to constitute a compact signal measurement component. With the proposed design, a general microcontroller can proceed with a signal level sense and control with very few CPU power.

摘要： In TV broadcasting environment, due to different settings in different TV stations, the sound level from each station may vary in a wide range. For general users, it may cause annoying experience since the TV sound level may change a lot when user switches the channel from one to the other. In addition, switching among TV reception and AV inputs may have similar problem. The present invention relates to a method and apparatus which can be easily integrated into a single IC to achieve a low cost TV sound level control solution.
