问题 I have two audio files that I need to merge on top of each other. Each mp3 is one side of a conversation, so in theory when I merge these two files together I should hear a complete conversation. Has anybody ever accomplished this in .Net? I've seen examples of people concatenating audio files together, but I repeat, I don't want to do that. I want to merge/mix two audio tracks so the are on the same audio file. Any help would be appreciated. I am looking at the NAudio library. Actual code

问题 Here's my problem: I'm writing a laravel backend which have to serve an mp3 file that had to be reproduced by using the android standard media player. For the laravel backend I need to use JWT to handle authentication so on every request headers I have to set the "Authorization" field to " Bearer {token} " . The laravel route is " /songs/{id} " and is handled in this way: public function getSong(Song $song) { $file = new File(storage_path()."/songs/".$song->path.".mp3"); $headers = array();

问题 I have made a small application to extract audio from an mp4 file, or simply convert an existing audio file to AAC/mp4 format (both raw AAC, or inside mp4 container). I have run this application with existing mp4 files as input, and it properly extracts audio, and encodes to mp4 (audio only:AAC), or even directly in AAC format (i.e. test.aac also works). But when I tried running it on mp3 files, output clip plays faster than it should be (a clip of 1:12 seconds plays back till 1:05 seconds

问题 I'd like my Android application to download an mp3 file from the internet and play it like a stream while downloading it. Is this even possible? How would I go about doing it? Essentially I want the user to be able to listen to the file instantly, but have it keep downloading to the SD Card even if he stops listening, so the whole mp3 file will end up on the SD Card either way. 回答1: I don't believe android provides the functionality you're asking for. But there's one workaround I know of that

问题 is there a way to convert my recorded .caf files to .mp3 using the iPhone SDK / Core Audio, something else? I've been looking around for a while, but all I've found was a command line uitility (which isn't allowed to run on the iPhone). Regards 回答1: Since the iPhone shouldn't really be used for processor intensive things such as audio conversion, have you thought about transferring those files to your computer and running the conversion there using the command line tool you mentioned? I'm
