report apply to any MSP430 MCU that has at least one ADC input and a DAC. 2 Compression and Decompression Algorithms The simplest way to make a voice recorder is to store the analog-to-digital conversion results (for example, 12-bit samples) directly in the flash memory. Most of the time, the audio data does not use the

embedded - Zlib compression on MSP430 - Stack Overflow
https://stackoverflow.com/questions/8856925/zlib-compression-on-msp430
According to MSP430 datasheets and Wikipedia article, you don't have enough RAM (it has at most 16 KiB) even for just sliding window (32 KiB). So, you cannot use any deflate algorithm for MSP430. Considering ZLIB is a just deflate implementation that's true for ZLIB too. Even you try to write your own deflate implementation you cannot succeeded.
