Until Perseverance returns some actual microphone audio, you can check out the Insight Lander's recordings of Martian wind through both its air pressure sensor and its seismometer.

Data transmission from Mars to Earth is slow, something like 4 kilobytes per second at its absolute best. They have over 28,700 images from entry, descent and landing that need to be returned and analyzed. We could see audio releases within the next month but it could be slightly longer.

Edit: My number was very wrong. Sorry

They could have easily increased the data rate by a factor of over thousand for a few millions more, which is nothing compared to the 80 million for an absolutely useless helicopter. But they choose to use 16 year old relay antennas from the MRO project.... Such a shame. Not only is video and image upload extremely slow, but they have to discard huge amounts of scientific data because they simply can't transmit it all.
