The computer configuration requirements for music production and arrangement are as follows:

1. Processor (CPU): Music production mainly relies on the performance of the CPU. It is recommended to choose at least a 4-core and 8-thread CPU. Such as i3 or i5 series. If budget allows, you can upgrade to the i7 or i9 series for better performance.

2. Memory (RAM): Memory is crucial to the performance of a music production computer. It is recommended to choose at least 8GB of memory. If you perform complex mixing and arranging work, you will need 16GB or more memory. If you have enough budget, you can buy 32GB or 64GB of memory.

3. Hard drive (Storage): It is recommended to use a solid-state drive (SSD) because its reading and writing speed is faster and it can better meet the needs of music production. The system disk must be at least 256GB. If you need to store a large number of audio sources, a storage capacity of at least 1TB is recommended.

4. Graphics card (GPU): For music production, the graphics card is not the most important component, but if you have extra budget, you can choose a moderate graphics card, such as GTX 1050 or higher performance graphics card.

5. Power Supply: It is very important to choose a reliable power supply. It is recommended to choose a power supply of at least 400 watts (W) to ensure the stable operation of the computer.

In addition to the above hardware configuration requirements, it is also recommended to install professional music production software, such as Ableton Live, FL Studio, etc. At the same time, it is also very helpful to understand the hardware and software related to music production.
