  • Forum Post: What is loopback and how does it work?

    Ron6621
    Loopback refers to taking the output of a device and routing it back to the input of the same device. For audio converters with an onboard DAC and ADC there are two kinds of loopback: digital and analog. When using digital loopback, the output of the device ADC is routed back into the input of the device...

  • Forum Post: Linux ALSA CODEC for TLV320AIC3254

    james whitsett
    We are building a product from the OMAP-L138 with an audio codec. For the protos we want to use the TLV320AIC3254 instead of the AIC3106 on the L138 development board. However time is critical and thus we are looking for the ALSA Codec for the TLV320AIC3254. In the beginning we only need the same capability...

    Fangyi Chen
    Hi, J Thanks for the reply. I have further questions in using the audio codec to generate a high frequency tone. 1. Sampling points. Despite the Nyquist, a sine wave may have to have more than 10 sampling point to show its shape. A codec dac is usually limited by its relatively low sampling rate...

    Paul45899
    I have a C6727 interfaced to a PCM3168 CODEC. The McASP outputs an 8 slot TDM frame of data with a single bit LRCLKDA. The problem is that the codec outputs the correct signal on channels 1 to 4 but nothing on channels 5 to 8. The CODEC setup is: SCKI = BCKDA = BCKAD = 8.192 MHz. LRCKDA = LRCKAD...

    I have an odd problem (pun intended) writing registers in Page 1 of the Codec. It originally seemed that I could not write to any odd address in Page 1. Everything works fine in Page 0. Upon further experimentation I discovered that a write to an odd address would complete after I wrote it's following...

    Hi, I am using the TLV320AIC3204 codec in an application where I need to accurately detect the time of arrival of an audio signal. At 44.1 kHz sampling rate I seem to get a 0.5ms delay from starting to transmit the data to the audio signal appearing on the line out and a 0.5ms delay at the ADC (audio...

  • Forum Post: AIC3204 low-frequency rolloff

    R. Jesup home
    I'm trying to figure out the source of a roll-off below around 800Hz with the AIC3204. The output from the line-out drivers (LOL/LOR) is flat, so I believe the output from the DACs is flat. However, the output from the headphone amps (HPL/HPR) has an extreme rolloff below around 800Hz. Rolloff is...

    I'd be curious to find out as well. I've got an application for the PCM2906B that require low power operation. The circuit works fine and draws only about 60mA, but the PCM2906 default descriptor asks for 500mA, so the device won't work with some low power hosts. What would it take to customize...

    hi MS so the decimation filter must be used, chosing among A filter, B filter and C filter. " The TLV320AIC3204 offers 3 different types of decimation filters. The integrated digital decimation filter removes high-frequency content and down samples the audio data from an initial sampling rate...
