[Embodiments] Hereinafter, embodiments will be explained in detail based on the drawings.

FIG. 2 shows a strength comparison display device according to an embodiment. In the figure, 10 is a storage means, and this storage means 10 stores music data of a large number of songs. Figure 3
As shown in the figure, each piece of music data is accompanied by vocal data, which is the data of the vocal part. These data are divided into many sections 1, 2, 3, etc., where one measure is one section.
They are divided into sections and arranged in the order in which the song progresses, and the vocal data is stored so that it precedes the music data by approximately one section. The vocal data includes strength data indicating the strength of the vocal part.

As shown by the long arrow in FIG. 3, a one-screen display code is inserted at the position where the screen should be updated, and the current position display code is inserted at the position where the current position should be shown, as shown by the short arrow in the figure. are inserted as appropriate. At the beginning of the vocal data, the horizontal axis unit time is written. This horizontal axis unit time is the maximum value of the number of current position display codes in each section. Furthermore, clear data is written at the end of the vocal data. This clear data clears the screen at the end of the song. The storage means 10 also stores character data for displaying lyrics in the form of character codes.

[0010] A playback device 60 is connected to the storage means 10, and reads music data from the storage means 10.
I'm trying to play this.

A decoder 21 is also connected to the storage means 10, and a vocal data extractor 2 is connected to the decoder 21.
2. A dynamic data extractor 23 and a buffer 41 are connected in sequence, the vocal data extractor 22 reads the vocal data attached to the music data, the dynamic data extractor 23 reads the dynamic data from the vocal data, and Buffer 41 for strength data for each section
Store in. Further, the decoder 21 includes a horizontal axis unit time extractor 42 that reads the horizontal axis unit time from the vocal data, and a single screen display code extractor 43 that reads the single screen display code.
, a clear data extractor 44 for reading clear data, and a current position display code extractor 45 for reading a current position display code are connected in parallel. and buffer 41,
Horizontal axis unit time extractor 42, single screen display code extractor 43,
Each output signal of the clear data extractor 44 and the delay means 45 is input to the graph drawing means 46. The output signal of the graph drawing means 46 is input to the image device 50. Further, the output signal of the one-screen display code extractor 43 is inputted to the buffer 41 as a trigger signal.

Next, detection of strength levels from actual vocals will be explained. In FIG. 2, reference numeral 31 denotes a known microphone for collecting the user's vocals. AD converters 37 are connected in this order, and the audio signal from the microphone 31 is amplified by a microphone amplifier 32, full-wave rectified by a full-wave rectifier 33, integrated by an integrator 34, and this signal is sent to a sample-and-hold device 36. Sample and hold the value. In that case, the sampling timing is determined by dividing the frequency of the current position display code by the frequency divider 3.
This is done using a signal frequency-divided by 5. The output signal of the sample/hold device 36 is subjected to AD conversion by an AD converter 37, and is then inputted to a graph drawing means 46 as a strength level.

The graph drawing means 46 constructs an image signal so that the image device 50 compares and displays the intensity data extracted from the vocal data and the intensity level obtained from the actual vocal. That is,
First, the horizontal axis size W of the image is determined based on the horizontal axis unit time read out by the horizontal axis unit time extractor 42. Next, the single-screen display code extracted by the single-screen display code extractor 43 raises the image signal and releases the strength data from the buffer 41, so that the strength data of one section becomes a solid line graph G as shown in FIG. appears on the screen before the music. Then, the current position within the section is indicated by a vertical line L in synchronization with the music based on the current position display code read out by the current position display code extractor 45, and the left and right sides of this vertical line L are color-coded. In other words, while viewing the solid line graph G of the strength data of one block in the background, the user moves the vertical line L of the current position from left to right within the solid line graph G, and the color of the screen changes after passing this vertical line. You can watch it.

In this case, as shown in FIG. 4, the strength level p sampled by the current position display code is displayed on the vertical line L. This strength level p is held as it is until one section of the screen is cleared, so the strength level p up to the current position is displayed as a broken line graph P on the screen, and at a glance it looks like a solid line graph G of strength data. can be compared with. That is, the user can check the strength level of his/her vocals using the broken line graph P, and compare this with the solid line graph G of strength data. Therefore, the user can judge the accuracy of his/her vocals in terms of strength and weakness.

When the next one-screen display code is read out, the screen is cleared, and the strength data of the next section is displayed on the screen as a solid line graph G. The current position is indicated by the current position display code, and the sampled strength level is displayed. The process shown by the broken line graph P is repeated. When the song ends, the screen will be cleared using clear data.

Note that the lyrics are also displayed on the image device 50 based on character data, but a description of the processing blocks will be omitted.

In the above configuration, the decoder 21, the vocal data extractor 22, and the dynamics data extractor 23 constitute a dynamics data reading means 20 that refers to the storage means 10 and reads out dynamics data. Also, a microphone 31, a microphone amplifier 32, a full-wave rectifier 33, an integrator 34, a frequency divider 35, a sample/hold device 36, and an AD converter 37 constitute a strength level detection means 30 that detects the strength level from an actual vocal. are doing. Further, a buffer 41, a horizontal axis unit time extractor 42, a one-screen display code extractor 43, a clear data extractor 44, a current position display code extractor 45, and a graph drawing means 46,
The image device 50 receives the outputs of the strength data reading means 20 and the strength level detection means 30, and compares and displays the strength data and the strength level in correspondence with the music data.
It constitutes a comparison display means 40 for controlling.

Note that the data may be composed of, for example, MIDI data. In that case, it is sufficient to allocate one channel each to music data and vocal data. At this time, the playback device 60 is a MIDI sound source, and the decoder 21 is a MIDI decoder.

Furthermore, in the above embodiment, one bar is defined as one section, but one section may be set using other standards.
