Hi,
This is in reference to audio encoding using aac-lc audio encoder over dm6467t target boards.
In our setup the aac-lc encoder is used in encoding analog audio input (2channel 48KHz I2S 16bit pcm data) received from audio decoder device.
When we play the PCM file in cool-edit utility we can hear a noise free audio.
But the same when encoded using aac-lc encoder and played using vlc player introduces noise. Can anyone provide us pointers on the AAC-LC encoder parameters that can help resolve this issue?
We are using following param and dynamic params:
Params:
sampleRate = 48000;
bitRate = 64000;
channelMode = IAUDIO_2_0;
dataEndianness = XDM_LE_16;
encMode = IAUDIO_CBR;
inputFormat = IAUDIO_INTERLEAVED;
inputBitsPerSample = 16;
maxBitRate = 192000;
dualMonoMode = IAUDIO_DUALMONO_LR;
crcFlag = XDAS_FALSE;
ancFlag = XDAS_FALSE;
lfeFlag = XDAS_FALSE;
Dynamic Params
bitRate = 64000;
sampleRate = 48000;
channelMode = IAUDIO_2_0;
lfeFlag = XDAS_FALSE;
dualMonoMode = IAUDIO_DUALMONO_LR;
inputBitsPerSample = 16;
Thanks in advance
