Compression of digital audio signals has become very important audio computation process. When audio data are compressed it is possible to store more data in a smaller memory and to increase the overall audio data throughput transferred through an interface. Several compression schemes were developed and well established. Most of them adopt the MDCT/IMDCT. This paper presents an software tool, an improved MDCT IP core generator with architectural model simulation that is capable to generate several MDCT architectures with adjustable parameters for FPGA-based design. The software tool has integrated functions of the computation precision and area estimation, which facilitate and speed up the design process.
