https://devzone.nordicsemi.com/f/nordic-q-a/72949/a-question-about-the-i2s-cyclehi , I am working on I2S to collect audio, and I need 2 nrf52833 to realize the intercom function. For these two nrf52833, the I2S clock is different. There are fast and slow. Is there any way to speed up or slow down his cycle without re-initializationen-USTelligent Community 13Wed, 24 Mar 2021 15:33:35 GMThttps://devzone.nordicsemi.com/thread/301744?ContentTypeID=1Wed, 24 Mar 2021 15:33:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:abc84c87-dd69-45f8-9730-a92011eaf34bKenneth<p>For the nRF52-series, to overcome underflow/overflow audio buffers then interpolating/discarding samples would be the solution. Interpolating/discarding samples can introduce distortion in audio, but are depended on the clock offset between peers and buffer size.</p> <p>The nRF53-series may be a better fit, since the nRF5340 has a dedicated audio clock. The MCK frequency can be adjusted on-the-fly for the nRF5340:&nbsp;<br /><a href="https://infocenter.nordicsemi.com/topic/ps_nrf5340/i2s.html#concept_ezd_bqy_vr">https://infocenter.nordicsemi.com/topic/ps_nrf5340/i2s.html#concept_ezd_bqy_vr</a>&nbsp;</p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/300809?ContentTypeID=1Fri, 19 Mar 2021 06:07:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9fcb116f-d133-4de8-af8c-0081a777d101Ellison<p>ok,thank!</p> <p>Ellison</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/300727?ContentTypeID=1Thu, 18 Mar 2021 14:46:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7fa147c4-b229-4f61-9f66-ddfbe6566216Kenneth<p>Let me look into this.</p> <p>Kenneth</p><div style="clear:both;"></div>
