TLV320ADC3101: Can its miniDSP support Reverb or Echo effect by customer algorithms?

Part Number: TLV320ADC3101


Hi Team,

Please kindly help on these questions. Many thanks.

According to below link comment: https://e2e.ti.com/support/audio/f/6/t/720285?tisearch=e2e-sitesearch&keymatch=TLV320ADC3101%20dsp

ADC3101 has limited miniDSP resources, so it can not support Reverb or Echo effect by TI embedded algorithms.

The Echo and reverb effects may be created manually using the basic miniDSP blocks available in PPS, where user can customize the process flow according to the available resources of the ADC3101's miniDSP.

Q1: Does it means customer can input their own algorithms by PPS tool to achieve Reverb or Echo effect, as long as the algorithm won't over ADC3101's miniDSP ability?

Q2: We want Reverb or Echo effect on one mic input, then mix with another line in, then I2S output. Can ADC3101 do this behavior?

Q3: Are there any ADC suggestion have DSP that have TI embedded algorithm can achieve Reverb or Echo effect?

Q4: Could you help to list a simple functions list that ADC3101's miniDSP can do by TI embedded algorithm?

Many thanks

  • Hi Daniel,

    The ADC3x01 devices do not support Reverb. if you drag and drop the ADC3x01 framework into the workspace, you will notice that the Reverb block will disappear. This is because the ADC3x01 devices do not have enough memory to support delay, reverb, chorus or flanger algorithms.

    The AIC326x devices do support the Reverb, however the algorithm is fixed and has only two parameters: Enable/Disable and Strength.

    At this time there are no other ADCs with programable DSPs in TI's portfolio.

    best regards,
