QUESTION
I am trying to read correctly a WAVE file, PCM, mono, 16 bits (2 bytes per sample). I have managed to read the header. The problem is reading (writing) the data part.
As far as I understand the 16-bit samples in the data chunk are little-endian, and "split" into two chunks of 8 bits each. So for me a way to read the correct data should be:
- Read file and put chunks into two different
int8_tvariables (or astd::vector..) - In some way "join" these two variables to make a
int16_tand being able to process it.
The problem is I have no idea on how to deal with the little-endianness and the fact that these samples aren't unsigned, so I can't use the << operator.
This is one of the test I've done, without success:
...ANSWER
Answered 2021-May-15 at 19:52I'm a Java programmer, not C++, but I've dealt with this often.
The PCM data is organized by frame. If it's mono, little-endian, 16-bit the first byte will be the lower half of the value, and the second byte will be the upper and include the sign bit. Big-endian will reverse the bytes. If it's stereo, a full frame (I think it's left then right but I'm not sure) is presented intact before moving on to the next frame.
I'm kind of amazed at all the code being shown. In Java, the following suffices for PCM encoded as signed values:
QUESTION
I want to make Siren sound which's frequency changing 960Hz and 770Hz every 0.65sec. (in 8sec Wav file) But I have no idea how to build function as I write above. I tried to use 'for(...=0; ... < 0.65; ...++)' every period. But y[0] and y[1] are function, so I'm confused. My final goal is to make siren wav sound, which come from right side to left side.
To say to the point, I want to know how to make frequency changeable 960Hz and 770Hz every 0.65 sec. I'll be thankful to you if you give me advice to achieve my final goal.
As I'm not good at English, if you're hard to understand my Question, plz comment me.
...ANSWER
Answered 2021-May-13 at 19:14You are outputting each of the two frequencies on alternate samples. That is, a steady tone of one frequency in the left channel and a steady tone of the other frequency in the right channel.
What we need to do is maintain the same frequency for a given sub-duration and flip between them. And, the same frequency is fed into both channels [albeit with different volume levels].
Here's a slight refactor that does that. It is annotated.
I'm not sure about the level you're using (e.g. level_l and level_r). I think it sounds better with them being the same (i.e. the siren gets closer), so I made level_r just be level_l as an option. But, I left the original L/R scaling intact.
Edit: After listening to the above, the siren sounded more like a true [European] siren when I shortened the sub-duration. I'm not sure it's still 0.65 seconds, but it sounded better [to me]
QUESTION
Working from a previous question asked. The main objective is reading a .wav file and specifically skipping the RIFF and other containers and focusing strictly on the data portion of the .wav file contents. The running example is encountering an error for:
AttributeError: 'numpy.ndarray' object has no attribute 'append'
- Stemming from a traceback of:
new_data = data.append(np.zeros(2 * sr))
However, when changing the below file to try and fix this issue, such as new_data.astype(np.int16), still running into issues.
ANSWER
Answered 2021-May-13 at 02:29ndarray doesn't have a method append, use numpy.append(arr1, arr2)

QUESTION
Learning how to modify different types of audio files, .wav, .mp3, etcetera using Python3 using the wave module. Specifically .wav file format, in this regard for this question. Presently, I know there are ISO standards for audio formats, and any references for this subject are greatly appreciated regarding audio standards for the .wav file format as well on a side note.
But in terms of my question, simply ignoring the RIFF, FMT headers, in a .wav file using the Python3 wave module import.
Is there a more efficient way to skip the RIFF headers, other containers, and go straight to the data container to modify its contents?
This crude example simply is converting a two-channel audio .wav file to a single-channel audio .wav file while modifying all values to (0, 0).

I have a url, http://127.0.0.1:8000/lesson/riff-lab/1305/pentab-wow/
When a user navigates to the above url, I want to change it to http://127.0.0.1:8000/lesson/riff-lab/1305/pentab-wow/?d:a3ugm6eyko59qhr/pentab-Track_1.js
The appended part is needed in order to load something that I want to load, but the specifics are not important for this question.
Here's what I have tried.
...ANSWER
Answered 2021-May-09 at 04:52You trying to change the aim of a shell that already has hit it's target. URL comes first, then view routed to it is processed, there is no way to change it without making another request, e.g. returning a redirect response "please open this url now" to the client.
You can easily find it in django docs by this keywords, but what you are trying to do generally doesn't look very reasonable, if you know beforehand how you need to construct url, why change it mid-way or why change it at all if view has all required data? I don't know your context, but it's probable that you need to reconsider your approach.
QUESTION
Is there a way to convert raw audio data (obtained by PyAudio module) into the form of virtual file (can be obtained by using python open() function), without saving it to the disk and read it from the disk? Details are provided as belows.
I'm using PyAudio to record audio, then it will be fed into a tensorflow model to get prediction. Currently, it works when I firstly save the recorded sound as .wav file on the disk, and then read it again to feed it into the model. Here is the code of recording and saving:

QUESTION
I am trying to set up xaudio2 and have been following the documentation. I can play a sound just fine, until I try playing it again, at which point nothing happens. I have followed the documentation almost line for line, but can't figure out why this is happening. here is the code.
...ANSWER
Answered 2021-Feb-24 at 21:35A single XAudio2 source voice can only be playing or not playing. It can't be playing 'twice'. If you want the same sound with overlapping playback, you need to have two XAudio2 source voices active. You can submit the same audio to as many different format-compatible voices as you want. Remember that your audio data remains in your applications' memory, and each source voice just reads it directly from there (i.e. there's no copying of all the source data like there was in DirectSound).
XAudio2 is a 'real-time mixer' for complex sounds like you find in games. If you just want to play a WAV file, that's what the old Win32 PlaySound function did.
If you want to play the same sound again, you have to submit the audio packet again. If you do it repeatedly, it will keep looping.
Alternatively, you can set the loop-count when you play it to just reuse the same submitted packet over and over again.
You should take a look at DirectX Tool Kit for Audio for a simple XAudio2-based audio library. It supports 'one-shot' sounds like you are trying to do here, as well as looping sounds, voice-management, positional audio, environmental effects, file-based streaming, etc.
