问题 I've been capturing audio using the loopback capture mode. The captured waveform is a 32 bit waveform. I'm struggling with converting this to a 16 bit waveform so encoders like lame can deal with it (it says Unsupported data format: 0x0003). I've tried shifting the bits (not my strong point) in the wave stream itself from 32 bit to 16 bit but the result still sounds distorted. The Wave32To16Stream class seems to blow up on this case: if (sourceStream.WaveFormat.Encoding != WaveFormatEncoding

问题 I have the following code: function playSound(source) { document.getElementById("sound_span").innerHTML = "<embed src='" + source + "' hidden=true autostart=true loop=false>"; } <span id="sound_span"></span> <button onclick="playSound('file.mp3');"></button> Once you click play, the MP3 gets downloaded, than it starts to play. However, it can take a while if it has like 1 MB. What I need is a preloaded (just like you can do with the images). So when the page loads, the mp3 will be streamed

问题 i'm kinda new in programming so i hope you can help me :) Lately, I've been trying to write sth that can change id3 tags of mp3 file. I managed to write code getting those tags quite easily, but i have no idea how to write code changing tags. I assumed that there may be no easy solution, so I decided to try out some libraries. It may be my fault, but none of them work.. Anyway, my question is : if it is quite simple - how to do my own id3 tag getting code? and if not, are there any libraries

问题 In my iOS application I'm trying to export an mp3 file from the iPod library to the app's documents directory on the device. Currently I'm trying to use AVAssetExportSession but it's not working for mp3 files. It works well for m4a files. Is exporting an mp3 file possible using AVAssetExportSession? What is the appropriate outputFileType for AVAssetExportSession? ( AVFileTypeAppleM4A works for m4a files) Thanks! 回答1: I am facing the same problem. Unfortunately, non of the iOS frameworks

问题 I am trying to record some audio and convert them to other sound formats. I am using AVAudioRecorder class to record and these are the recording settings I used.. NSDictionary *recordSetting = [[NSMutableDictionary alloc] init]; [recordSetting setValue:[NSNumber numberWithInt:kAudioFormatLinearPCM] forKey:AVFormatIDKey];//kAudioFormatMicrosoftGSM,kAudioFormatLinearPCM [recordSetting setValue:[NSNumber numberWithFloat:8000] forKey:AVSampleRateKey]; [recordSetting setValue:[NSNumber

问题 I need to build a web script that converts a mp3 file to a waveform image, and I came across this website. I’ve uploaded the PHP file and .dll and .exe file from LAMB to my website (hosted by host monster). But when I try uploading the MP3 file on the website, it just generates a black image instead of the waveform image. I have little knowledge of PHP, so I don’t exactly know what’s wrong, but I’m guessing it has to do with the uploading part of the program. Could anybody tell me what is

问题 I have been struggling for several hours about this. http://www.mysecretathens.gr/Sera/releases.html I am working on this project for a musician and the mp3 songs dont play in Firefox. Chrome, even IE plays them. Do you know why? Doesn't it support mp3 files? In the documentation of the script it says that you should also have .wav sounds of each file but I have around 25 songs and if I also upload the .wav sounds it would be too heavy. Is there a golden solution? Can I do something so that

问题 I want to get an clean Mp3 File, without any aditional data like id Tags, Cover Image, encoder info or what else. Just the mp3 in an valid file, wich can play every mp3 player. I started with this one: Access MP3 audio data independently of ID3 tags? http://code.google.com/p/kodebucket/source/browse/trunk/bin/mp3dump.rb It works nice to get an valid hash of the mp3 without id Tags, but when you save the output into an mp3 file, it's broken. Maybe you have there an idea, how to get this work.

问题 Mediaplayer didn't work for me, so I moved to a simple test project (C# Console App).
