 note = {楽器やオーディオ機器にフィルタを実装するいくつかの方法の中で，特性の自由度の高いフィルタを構成したい場合は FIR フィルタを用いることがあり，この FIR フィルタの計算効率を上げるために高速畳込が用いられる．私たちは，これまで数チャネルまでのソフトウェア実装が多かった高速畳込を 1024 チャンネルの実時間処理を行えるよう FPGA 上に実装した．ここではその実装にあたり，楽器・オーディオにおける畳込を用いた応用の制約について議論し，オーディオ処理特有の工夫と FFT/IFFT 回路に実装した機能について説明し，今回行った実装の 1 例を紹介する．, In the various methods of implementing filters in musical instruments and audio products, if one desires to construct a filter with a high degree of characteristic of flexibility, an FIR filter may be used. When implementing an FIR filter, a method that uses fast convolution to improve computational efficiency is often employed. We implemented a circuit on an FPGA that processes this fast convolution in real-time across 1024 channels. In the implementation, we discuss the constraints of applications using convolution in musical instruments and audio, and describe the features implemented in the FFT/IFFT circuit, as well as the unique ingenuity specific to audio processing. We will also introduce an example of the implementation carried out this time.},
