As @Pavel explained, it is not simply possible to traverse a record, like you could traverse an array. But there are several ways around it – depending on your exact requirements. Ultimately, since you want to return all values in the same column, you need to cast them to the same type – text is … Read more
There is nothing in the Python 2.x file object, or the Python 3.3 io classes, that lets you specify a custom delimiter for readline. (The for line in file is ultimately using the same code as readline.) But it’s pretty easy to build it yourself. For example: def delimited(file, delimiter=”\n”, bufsize=4096): buf=”” while True: newbuf … Read more
Thanks everyone! Based on this information, I reduced this to : RBits = record public BaseMid: BYTE; private Flags: WORD; function GetBits(const aIndex: Integer): Integer; procedure SetBits(const aIndex: Integer; const aValue: Integer); public BaseHi: BYTE; property _Type: Integer index $0005 read GetBits write SetBits; // 5 bits at offset 0 property Dpl: Integer index $0502 … Read more
You could try something like this: based on this question/answer # this is the threshold that determines whether or not sound is detected THRESHOLD = 0 #open your audio stream # wait until the sound data breaks some level threshold while True: data = stream.read(chunk) # check level against threshold, you’ll have to write getLevel() … Read more
There’s a work around for saving .mp3 files using MediaRecorder. Here’s how: recorder = new MediaRecorder(); recorder.setAudioSource(MediaRecorder.AudioSource.MIC); recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4); recorder.setOutputFile(Environment.getExternalStorageDirectory() .getAbsolutePath() + “/myrecording.mp3”); recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC); recorder.prepare(); recorder.start(); The important part here is the setOuputFormat and the setAudioEncoder. Apparently MediaRecorder records playable mp3 if you’re using MediaRecorder.OutputFormat.MPEG_4 and MediaRecorder.AudioEncoder.AAC together. Hope this helps somebody. Of course, if you’d … Read more
I had the same problem, and I fix it just by enable/disable the access to the microphone in Setting>Confidentiality>Microphone (on Windows 10)
Ok I finally solved it. The problem was that I was setting up the AVAudioRecorder and file the path in the viewLoad of my ViewController.m overwriting existing files with the same name. After recording and saving the audio to file and stopping the app, I could find the file in Finder. (/Users/xxxxx/Library/Application Support/iPhone Simulator/6.0/Applications/0F107E80-27E3-4F7C-AB07-9465B575EDAB/Documents/sound1.caf) When … Read more
Since “Rec” is a property, the compiler treats it a little differently because it has to first evaluate the “read” of the property decl. Consider this, which is semantically equivalent to your example: … property Rec: TRec read GetRec write FRec; … If you look at it like this, you can see that the first … Read more
To avoid latency issues, you will have to work at a lower level than AVFoundation alright. Check out this sample code from Apple – Auriotouch. It uses Remote I/O.
I have contacted an engineer at Apple’s support and he told me that simultaneous AVCaptureVideoDataOutput + AVCaptureMovieFileOutput use is not supported. I don’t know if they will support it in the future, but he used the word “not supported at this time”. I encourage you to fill a bug report / feature request on this, … Read more
