avfoundation - Getting and setting playback position AVAudioEngine -

-

वापस जब AVAudioPlayer का उपयोग किया गया था, तो currentPosition का उपयोग किया जाता था & amp; स्थिति सेट करें, लेकिन जब AVAudioEngine & amp; AVAudioPlayerNode का उपयोग किया जाता है?

AVAudioEngine AVAudioPlayer से अधिक जटिल है। इसलिए मौजूदा स्थिति को जानने के लिए आपको नमूना टाइम / नमूना का उपयोग करना चाहिए नमूना टाइम AVAudioPlayerNode के अंतिम रेन्डरटाइम में पाया जाता है और sampleRate AVAudioFile की फ़ाइल स्वरूप में पाया जाता है।

इसके अलावा, यदि आप वर्तमान स्थिति को सेट करना चाहते हैं, तो आपको प्लेयर में डेटा स्ट्रीम करने के लिए एवाडियओपीसीबीफ़ेर का उपयोग करना होगा। फिर फ़ाइल सूचक को आगे बढ़ने के लिए AVAudioFile की फ्रेम रचना संपत्ति सेट करें का उपयोग करें।

I was trying to write a solution, which is a different and a manual for calculating a mean and STD The way. I have created a = ["Apple", "Banana", "Cherry", "Apple"] B = [3,4,7,3] C = [5,4,1,4] D = [7,8,3,7] Pd DF = PD to import pandals DataFrame (index = class (4), column = list ("ABCD")) DF ["A"] = A DF ["B"] = BDF ["C"] = C DF ["D"] = D Again, I made a list of A duplication. Then I went through the group all the time of the objects and calculated the solution. import as np l = list (set (df.A)) df.groupby ('A', As_index = False) listMean = [0] * len (df.C) ListSTD = [0] * L in the LAN (df.C) X: s = np.mean (df [df ['A'] == x] for C =.) = Z = [index for index, enumerate In the object (df ['a']. Value] x == item i for z: listMean [i] = s in: s = np.std (df [df ['a'] == X] .cvalues) z = index for index, enumerate item (df ['a']. Value) if x ==...
