[Claims]
1. A waveform data storage means for storing waveform data,
An input means for inputting the time-axis compression / expansion amount of the waveform data, and
Flexibility information generating means for generating flexibility information indicating flexibility, which is the degree of correction of the compression / expansion amount, for at least a part of the waveform data.
A correction means for correcting the compression / expansion amount based on the flexibility information, and
A waveform processing means that performs time-axis compression / expansion processing on the waveform data based on the modified compression / expansion amount.
Waveform processing device to have.
2. In the waveform processing apparatus according to claim 1, the waveform data is composed of a plurality of sections, and the flexibility information generating means is used for at least two sections of the plurality of sections of the waveform data, respectively. A waveform processing device that has flexibility information, and the flexibility information for each of these two sections is different from each other.
3. In the waveform processing apparatus according to claim 1 or 2, the waveform processing means is the length of the waveform data subjected to time-axis compression / expansion processing based on the compression / expansion amount corrected by the flexibility information. The feature is that the time axis compression / expansion processing is performed so that the length of the waveform data when the time axis compression / expansion processing is performed based on the compression / expansion amount that is not corrected by the flexibility information matches. Waveform processing device.

なお、前記波形データを、複数の区間によって構成し、前記柔軟度情報発生手段は、前記波形データの複数の区間の少なくとも2つの区間に対してそれぞれ前記柔軟度を有し、かつ、これら2つの区間に対するそれぞれの柔軟度情報は、互いに異なったものとすることができる。従って、或る区間において圧縮伸長された波形データは、他の区間の圧縮伸長された波形データと、圧縮伸長量が異なったものとなる。 Incidentally, the waveform data is constituted by a plurality of sections, the flexibility information generating means has the flexibility, respectively for at least two sections of a plurality of sections of the waveform data, and, of these two The flexibility information for each interval can be different from each other. Therefore, the waveform data compressed and decompressed in a certain section has a different amount of compression and decompression from the waveform data compressed and decompressed in another section.

前記波形処理手段は、前記柔軟度によって修正された前記圧縮伸長量に基づいて時間軸圧縮伸長処理された前記波形データの長さと、前記柔軟度情報によって修正されていない前記圧縮伸長量に基づいて時間軸圧縮伸長処理されたときの前記波形データの長さとが、一致するように、時間軸圧縮伸長処理を施すこともできる。これは、例えば柔軟度情報発生手段が、波形データの各区間の長さと各区間に対応する柔軟度情報との積の和が、全区間の長さとなるような柔軟度情報を各区間ごとに発生することによって達成できる。 The waveform processing means is based on the length of the waveform data that has been subjected to time-axis compression / expansion processing based on the compression / expansion amount that has been corrected by the flexibility, and the compression / expansion amount that has not been modified by the flexibility information. It is also possible to perform the time axis compression / expansion processing so that the length of the waveform data when the time axis compression / expansion processing is performed matches. This is because, for example, the flexibility information generating means provides flexibility information for each section so that the sum of the products of the length of each section of the waveform data and the flexibility information corresponding to each section is the length of the entire section. It can be achieved by occurring.
