* Combination of fullrate and quadro-output actually leads to buffer underruns
* Minimum controller required: ATmega368. ATmega168 is too low on RAM.
=== Alternatives ===
Now there is an alternative library called '''TMRpcm''' that does something similar: https://github.com/TMRh20/TMRpcm/wiki . This is a little bit easier to use (no conversion of WAV file needed). Here a table with the differences:
{|
!Feature!!SimpleSDAudio!!TMRpcm
|-
|Highest sampling rate||X||-
|-
|Native WAV playback (no file conversion needed)||-||X
|-
|Highly speed-optimized code (using Assembler for audio core)||X||-
|-
|Size optimized using minimal SD-FAT library||X||-
|-
|Universal SD library in the background supporting framentated files and many other uses||-||X
|-
|Stereo operation possible||X||X
|-
|Quad speaker operation possible||X||X
|-
|Volume seting support||-||X
|}
So depending on your needs, try the library that best fit your needs. TMRpcm might be easier for beginners. Both libraries should work with the same connections. You can take the information about the connections from here and use the TMRpcm library with that.
