السلام عليكم 

محاولة ثانية باستعمال مكتبة bass 

كود :

https://github.com/TDDung/DelphiFMX-BASS

record to buffer 
read 
play

فى المرفق اسسيات فقط كمدخل للتعامل مع المكتبة فى الاندرويد 
مثلا يمكن ارسال الصوت عبر udp ...
 (live chat audio ...)

[haniid]

نفس المثال السابق بدون استعمال المكتبة bass
