CCS: Know about which microelectronic is good for voice logger

Tool/software: Code Composer Studio

Hi all,

I trust you are doing well.

I want help with Audio processing for the multichannel Arm cortex M4 based device.

The process includes

4 channels detecting inputs all the time.

if there is audio coming from any or all ports of the device, the microcontroller should allow the audio coming from ports to be saved in a file on any memory space (Sd card preferred) which can then be played by inbuilt or external DAC by selecting from the menu displayed on LCD attached.

Also, I would mainly need your support only in the Conversion of audio to digital after detecting on ports, the complication for me arrives in multichannel parallel processing of audio, How the sampling must be done?

Also USB intergration.

Also, GSm terminals give gsm line input using a gsm sim card.

I want to which microcontroller I have to choose.

Stay safe

Thanks and regards

Shikhar

  • Hi Shikhar,

    You can look at the MSP432P family of MCUs at https://www.ti.com/microcontrollers/simplelink-mcus/products.html#p367=Host%20MCUs

    The specific microcontroller depends on the total amount of memory you need during the conversion to digital before writing to the SD card. How much audio duration for each channel, do you need to temporarily hold in the on-chip SRAM before the write to SD card for each of the Audio channels?

  • Thanks, Sir,

    Sir, you suggest to me how much audio duration for each channel works properly, based on that which development board is good to purchase.

    Compression rate of 64/12 KB per second or lower.

    Please suggest any reference material for the conversion of audion into digital or vice versa and how to store it into the memory card.

    Voice LoggervCompatible with USB Capable of Recording on PSTN Line directly and GSM through GSM terminal - 32 channels.

    Stay safe

  • Hi Shikhar,

    I cannot find any TI sw that is Voice Logger compatible.
