** Requirements for mono wav file **
1. Audio format: should be 1 for PCM
2. Sample rate: 48000 Hz (code expects this)
3. Bit depth: 16-bit
4. Block align: typically 2 for 16-bit mono 4 for 16-bit stereo

Steps for temp storage and play:
A. Convert wav files using ffmpeg:
	# Convert to proper PCM format
	ffmpeg -i "beep.mp3" -acodec pcm_s16le -ac 1 -ar 48000 "beep.wav"

B. Convert wav to a header file:
	xxd -i tone.wav > tone.h
