I have just read the specifications for the profiles of audio encoding for producer 9.2 M6 and I notice that as for video it has possibility of activating < encodingComplexity > for audio stream ...

https://producerapps.helixcommunity.org/cmdproducer/docs/AudienceFile.htm#encodingComplexity-rn-realaudio

However in the various profiles of audio encodings as for AutoRV9 1.3 this function is not activated ...

<?xml version="1.0"?>
<audience>
<avgBitrate type="uint">0</avgBitrate>
<maxBitrate type="uint">0</maxBitrate>
<streams>
<audioStream>
<pluginName type="string">rn-audiocodec-realaudio</pluginName>
<codecName type="string">cook</codecName>
<codecFlavor type="uint">32</codecFlavor>
<streamContext type="bag">
<presentationType type="string">audio-only</presentationType>
<audioMode type="string">music</audioMode>
</streamContext>
</audioStream>
</streams>
</audience>

did not can one rather use this kind of profile to gain in audio quality ... ?!!

<?xml version="1.0"?>
<audience>
<avgBitrate type="uint">0</avgBitrate>
<maxBitrate type="uint">0</maxBitrate>
<streams>
<audioStream>
<pluginName type="string">rn-audiocodec-realaudio</pluginName>
<codecName type="string">cook</codecName>
<codecFlavor type="uint">32</codecFlavor>
<encodingComplexity type="string">very-high</encodingComplexity>
<streamContext type="bag">
<presentationType type="string">audio-only</presentationType>
<audioMode type="string">music</audioMode>
</streamContext>
</audioStream>
</streams>
</audience>

some text from that link:

This property is only enabled for RealVideo 9 (rv9). This property is ignored for RealVideo 8 (rv8) and RealVideo G2 SVT (rvg2svt) codecs.

but what about audio? IMO it won't work with it. Audio codecs hasn't been change since the 5.1.

encodingComplexity works for RALF, RealAudio Lossless Format, not for RA8. It is not possible to increase RA8 quality further without algorithmic and bitstream changes.
