OK, so, do you understand you correctly - there is no segmentationfault in this case ?
What does the "Speicherzugriffsfehler" word mean ?
Regarding the
"instantiateMChMBEq :INFO: actual 00 band bin number: 2 frequency:23,4375Hzmbeq_119700: !!! ERROR !!! 28.2842712474619Hz band is too close toprevious one (gets into the same FFT bin)mbeq_119700: either change the frequency or increase number of point isFFT"
message - it says what it says - you can't have such close frequenciesunder given conditions.
If you want to use the original 48KHz sampling rate, increase frequencydistance between the the controls in the lower part, i.e. modifythe
36 $MBEQ::__config_hash{bands_sub} = 37 sub 38 { 39 my $min_frequency = 20; 40 my $max_frequency = 21050; 41 42 my @frequencies; 43 44 my $frequency = $min_frequency; 45 push @frequencies, $frequency; 46 47 $frequency = $min_frequency * sqrt(2); 48 49 push @frequencies, $frequency; 50 51 $frequency = $min_frequency * 2; 52 53 push @frequencies, $frequency; 54 55 56 my $ctr = 1; 57 for(;;) 58 { 59 $frequency *= (2 ** (1/3)); 60 61 if($frequency >= $max_frequency) 62 { 63 last; 64 } 65 66 push @frequencies, $frequency; 67 } # while($frequency < $max_frequency) 68 69 warn "\@frequencies=@frequencies"; 70 71 @frequencies; 72 };
subroutine.
Try, for example, to comment out line numbers 47, 49, so yourfrequencies will become 20Hz, 40Hz and on with 1/3 octave step.
...
Please also change the
378 static void cleanupMChMBEq(LADSPA_Handle instance) 379 { 380 MChMBEq *plugin_data = (MChMBEq *)instance; 381 382 // PERL_BEGIN 383 foreach my $suffix(@{$MBEQ::__config_hash{channel_suffixes}}) 384 { 385 print <<EOD 386 387 free((*plugin_data).out_fifo$suffix); 388 free((*plugin_data).out_accum$suffix); 389 free((*plugin_data).comp$suffix); 390 free((*plugin_data).real$suffix); 391 392 free((*plugin_data).input$suffix); 393 free((*plugin_data).output$suffix); 394 free((*plugin_data).in_fifo$suffix); 395 396 EOD 397 ; 398 } # foreach my $suffix(@{$MBEQ::__config_hash{channel_suffixes}}) 399 // PERL_END 400 401 free((*plugin_data).window_for_input); 402 free((*plugin_data).db_table); 403 free((*plugin_data).cos_times_gain); 404 free(instance); 405 } // static void cleanupMChMBEq(LADSPA_Handle instance)
subroutine, please remove the
392 free((*plugin_data).input$suffix); 393 free((*plugin_data).output$suffix);
line - I'm not the one who allocates input and outputbuffers, so I shouldn't deallocate them.
I don't think you have had a problem with this so far - becausethe problem can occur only when cleanupMChMBEq is called and after,and it wasn't yet the case.
