PhonoEQ 2016-03-05 18:30:13 I quickly made (using Cycling74's Max/MSP) a fully working prototype demo of PhonoEQ software which I'm going to release ... tomorrow. This prototype works best at sampling frequencies above 88.2kHz because of the method used for to compute the biquad filter coefficients. Final release runs internally at 384kHz to get the EQ response to about ideal. Magnitude error at 96kHz:ATM, there's- input can be taken from ADC or audio file (few audio file formats supported)- recording the output (few audio file formats supported)- 38 presets for RIAA and non-RIAA equalizations + custom preset so it's possible tweak those frequencies (see below)- Remove RIAA is usable when recording non-RIAA record through RIAA pre-amp/circuit- 4th order butterworth highpass as rumble filter (24dB/Oct at 20Hz)- Neumann and IEC poles for RIAA (custom preset lets to use these freely)- filter gain control is done through filter gain coefficients (i.e. in use only when eq filter is in use)Probably there's not many here who needs this type of software but if something comes in to mind, any suggestions for additional features would be great. Project DL links coming later.JuhaBTW, looks like this new editor isn't working smoothly with IE11!
