Sound signal processor

Abstract

In an audio signal processing device which processes audio signals and outputs the audio signals, setting controls (118), such as filter controls (11), for setting values of parameters for the signal processing and a display (13, 24, 34) for presenting information by the presence or absence and the style of lighting of LEDs is provided, in which when scene data stored in a scene memory is loaded, the display style of the display (13, 24, 34) is made different in accordance with match / mismatch between a current set value of the parameter and the value of the parameter relating to the loaded scene data. Alternatively, the display (13, 24, 34) is made to simultaneously present the loaded value and the value at the time of the loading in different display styles.

Description

technical field [0001] The present invention relates to an audio signal processing device that performs signal processing on an audio signal and outputs it, and particularly relates to an audio signal processing device that is characterized in display control of a display unit. Background technique [0002] In an audio signal processing device such as a digital mixer that performs signal processing on an audio signal and outputs it, conventionally, a corresponding display is provided near the setting operation member for setting the parameter value of the signal processing to display The parameter value set by the operating part (referring to Japanese Patent Application Publication No. 2002-319915, especially referring to paragraph 0031 and Figure 8 ). [0003] As such a display, a display device that presents information based on whether a light source such as an LED (light emitting diode) is on or not is used. There are a plurality of LEDs, which are used as indicators r...

Problems solved by technology

However, this operation is cumbersome and time-consuming. Once the scene data is reflected to the signal processing, the operator must store the changed place afterwards.

[0009] In the actual use of digital mixers, it is often necessary to create a plurality of scene data in which only some of the values ​​of the parameters have been changed, and then call them out for use in order to grasp the parameters of the called out scene data. There is a strong requirement of where the value differs from the value set before recalling, but, as mentioned above, this requirement cannot be fully satisfied in the conventional digital mixer
