Product Comparisons

· NEM compared to AAC (the iTunes codec) and AAC+/HE-AAC V1:

· AAC+/HE-AAC V1 is 4-fold more complex than NEM.

· AAC+/HE-AAC V1 can not run on low end processors due to its high complexity — NEM decoder does run on low end ARM 7 processors.

· AAC+/HE-AAC V1 audio quality is inferior or equal to NEM.

· AAC (iTunes) is >3-fold more complex than NEM.

· AAC (iTunes) audio quality is substantially lower than NEM.

· NEMx compared to AAC+/HE-AAC V1, eAAC+/HE-AAC v2, and AMR-WB+:

· AAC+/HE-AAC V1 is 37% more complex than NEMx.

· AAC+/HE-AAC V1 audio quality is substantially lower than NEMx.

· eAAC+/HE-AAC v2 is 66% more complex than NEMx.

· eAAC+/HE-AAC v2 audio quality is significantly lower than NEMx; NEMx at a 20% lower bitrate achieves the same audio quality as eAAC+/HE-AAC v2.

· AMR-WB+ is more complex than NEMx.

· AMR-WB+ audio quality is substantially lower than NEMx.

· Putting it all together:

Both NEM and NEMx offer substantially lower complexity and higher audio quality at lower bitrates than all their competitors.
