Please add the symbol for ELECTRET_MIC_EE to the EasyEDA Libs with user adjustable `lf`, `hf` and `Sens_dBV` values in the Properties panel. >lf represents the low frequency -3dB rolloff in Hz; >hf represents the high frequency -3dB rolloff in Hz; >Sens_dBV represents the microphone sensitivity in dBV. Default values are: >lf = 20 >hf = 20k >Sens_dBV = -42 The spice model for ELECTRET_MIC_EE is in the library but does not yet have the correct syntax to accept parameters via the Properties panel. * This model is demonstrated in: ><https://easyeda.com/file_view_Electret-microphone-model-test-jig_7nhbtL3le.htm> and: ><https://easyeda.com/file_view_Sound-operated-flash-02_gwu0hztL3.htm>
