angeloseme / ofxlibsndfilerecorder Goto Github PK

hi angelo,

thanks for developing this of library, it worked out of the box for me on osx 10.7.2 / xcode 4.1 / openframeworks 007 github develop branche 2012-04.

i tested the example in Apple Instruments for memory leaks and allocations and i detected a memory leak in
ofxLibsndFileRecorder::setup(string fileName, int sampleRate_, int numChannels_)
on
outFile=new SndfileHandle(ofToDataPath(fileName,true),SFM_RDWR, audioFormat, numChannels, sampleRate);

outFile is never cleaned out before creating the new SndfileHandle in a new recording.

so i in ofxLibsndFileRecorder.cpp for void ofxLibsndFileRecorder::finalize(){
i added as last line within the if(initialized){ statement (line 59 in ofxLibsndfileRecorder.cpp)

delete outFile;

testing it again in instuments showed the memory leak was gone.

you might want to test it out for yourself and add this fix to the repository when affirmitive.

thanks for your attention reading this message.

best regards,

arne.

My Code is
# -- coding: UTF-8 --
from scikits.audiolab import Sndfile
from os import walk, path, stat

track1 =  r'C:\Users\Furqan\Desktop\test\查找問題daw\查找問題d.wav'
#track2 = r'C:\Users\Furqan\Desktop\test\DAW\1.wav'

try:
    track_one_file_obj = Sndfile(track1, 'r')
except:
    print('Simple didnt work')
    pass

try:
    track_one_file_obj = Sndfile(track1.decode('cp1252'), 'r')
except:
    print('cp1252 didnt work')
    pass

try:
    track_one_file_obj = Sndfile(track1.encode('utf-8'), 'r')
    print(track_one_file_obj)
except:
    print('encode didnt work')
    pass


try:
    track_one_file_obj = Sndfile(track1.encode('utf8'), 'r')
    print(track_one_file_obj)
except:
    print('encode didnt work')
    pass

try:
    track_one_file_obj = Sndfile(track1.decode('utf-8'), 'r')
    print(track_one_file_obj)
except:
    print('decode didnt work')
    pass

greetings angeloseme,

the error i'm getting is

/Applications/of_v0.10.1_osx_release/addons/ofxLibsndfileRecorder/src/ofxLibsndFileRecorder.cpp:21:28: No matching function for call to 'ofToDataPath'

not sure how to fix it.

thanks for your advice and help!

Hi,

Thanks for the useful library.

I have been trying to record at 16000MHz with no luck, only 44100 works... Any ideas on how this issue can be addressed?
