mp3

问题 I am recording audio from mic and save it to .mp4 - it is AMR format. How to convert this audio to mp3 or AAC? I saw this post and I did not understand it - I am new in android. Is there some easy library for android that can work with mp3? I googled whole day and not found nothing. Maybe some good man can explain and give full example in this post and hundreds of people will be grateful! Thank you. 回答1: You could do that with http://www.javazoom.net/mp3spi/mp3spi.html probably. I am not sure

Here is the code: def speech(self, response): audio_file = "response.mp3" tts = gTTS(text=str(response), lang="en") tts.save(audio_file) pygame.mixer.init() pygame.mixer.music.load(audio_file) pygame.mixer.music.play() Error is on the tts

问题 I've basically created an application where i'm storing all mp3 data into Realm database here all data which are into string are fetched and stored really fast but when it comes to fetching and storing the images into byte array it's taking really long for my application to fetch and store the images into database which is eventually making my application lag. Below is my code which i have done please take a look. //This method is for getting song lists where i'm facing issues. Note: I'm

InputStream data = c.getResources().openRawResource(resId); Bitstream bitstream = new Bitstream(data); Decoder decoder = new Decoder(); while(thereIsData) { Head frameHeader = bitstream.readFrame(); SampleBuffer buffer = (SampleBuffer) decoder.decodeFrame

问题 I must concat 2 or more audio (wav or mp3) files and get one audio file. How can I do that in android? Thanks in advance. 回答1: The below code section will work as how many selections have been made.Selection means how much files are selected. Put your two wav files in /sdcard0/SSoftAudioFiles/ as 1.wav and 2.wav. And Just execute this method. public void SSoftAudCombine() { try { String[] selection=new String[2]; selection[0]="1.wav"; selection[1]="2.wav"; DataOutputStream amplifyOutputStream
