【Ochiq kodli】T5L asosidagi aralashtirish konsoli mikrofonlari uchun reverb va echo boshqaruvi

——Dan DWIN Dasturchilar forumi

Bugun DWIN dasturchilar forumidan mukofotga sazovor bo'lgan ochiq kodli ishni taqdim etishdan mamnunmiz: T5L chipiga asoslangan konsol mikrofonini aralashtirish uchun reverb va echo boshqaruvi. Bizning muhandisimiz T5L ning UART 4 ​​orqali reverb ishlab chiqish platasi bilan o'zaro ishlash uchun 800x480 o'lchamdagi displeydan foydalanadi, bu esa yuqori darajadagi audio effektlar uchun reverb, echo, nam tovush, quruq tovush, akustik, parchalanish va kechikish kabi muhim audio parametrlarini aniq sozlash imkonini beradi.
