We have detected a problem on several of your acquisition cards (MCH Streamer Lite).
On all the acquisition cards that we had ordered as part of our work, none seems to achieve the characteristics noted in the technical data sheet. The problem noted concerns especially the sampling frequency. We encounter enormous difficulties in making recordings at 48 kHz. The maximum performance that the card can reach is 44100 Hz, at this frequency the sound is of poor quality considering the requirement of the study we are conducting. If this is an issue known to your service let us know. We really need technical support to get out of this impasse. A proof of concept or video examples of a configuration that works at 48 kHz on PDM type Microphones, we will be of great use to move forward. We then started following the instructions in the user manual. 1. -Installation and configuration of the Driver 2. -Firmware installation,we had tested all these firmware none of them allows to go up to 48kHz • MCHStreamer_16i0o_sn19_PDM_v1.9a_up.bin • MCHStreamer_16i0o_sn20_PDM_v1.9a_up.bin • MCHStreamer_16i2o_sn25_PDM_IN_TOSLINK_OUT_v1.9a_up.bin We look forward to your response. Thank you for your availability and the quality of your service. |
