Requirements

Follow the tutorials to create a project and get your host, access_key and access_secret.

• How to identify songs by sound

• How to detect custom audio content by sound

Windows Runtime Library

If you run the SDK on Windows, you must install this library.
X86: download and install Library(windows/vcredist_x86.exe)
x64: download and install Library(windows/vcredist_x64.exe)

Note

1. If you run the SDK on Windows, you must install library(vcredist).

Install modules

Note: If you use nginx/apache, you can add "phpinfo()" in your code, and find extension dir and the path of "php.ini" from the result info

1. Find your extension dir, run(this is default extension dir):
   

$ php -ini | grep "extension_dir"
extension_dir => /usr/lib64/php/modules => /usr/lib64/php/modules

2. Put "acrcloud_extr_tool.so" to /usr/lib64/php/modules;(Your extension dir)
   
3. Find your path of php.ini file:

$ php -ini | grep "php.ini" 
Loaded Configuration File => /etc/php.ini

4. Modify file "/etc/php.ini"(Your php.ini)
   

extension=acrcloud_extr_tool.so
