Use microphone recording to save and replay in unity

Recording class

The Microphonemanager contains start recording, stop recording, play recording, and save the recording.

Save the recording

Wavutility is the saving and reading of recording data, which can be saved as a local file. wav or byte array for transmission. This stuff I found on GitHub, because the code is too long to be posted, the URL put on: Https://github.com/deadlyfingers/UnityWav

Important method

-Use the "Toaudioclip" method for loading WAV file/bytes.
Loads. WAV (PCM uncompressed) files at 8,16,24 and all bits and converts data to Unity ' s audioclip.
-Use the "Fromaudioclip" method for saving WAV file/bytes.
Converts an AudioClip ' s float data to wav byte array at + bit.

public static AudioClip Toaudioclip (String filePath)

public static AudioClip Toaudioclip (byte[] filebytes, int offsetsamples = 0, String name = "wav")

public static byte[] Fromaudioclip (AudioClip audioclip)

public static byte[] Fromaudioclip (audioclip audioclip,string filepath,string filename, bool SaveAsFile = TRUE)

Playback of recordings

In order to facilitate playback, and not to introduce additional files to record the playback time and recording of the corresponding information, the recording time as a file name (ex:170515-114114-676), and at the beginning of the record an empty recording as the starting time, the playback code is as follows:

IEnumerator Playaudioclip () {string[] files =Directory.GetFiles (Savepath); if(Files. Length >0) {List<string> temp =Newlist<string>();  for(inti =0; I < files. Length; i++)            {                if(!files[i]. Contains (". Meta") temp.            ADD (Files[i]); }            string[] Audiofiles =temp.            ToArray ();            Array.Sort (audiofiles); floatInterval =0f;  for(inti =0; I < audiofiles.length-1; i++) {AudioClip clip=microphonemanager.getinstance ().                Read (Audiofiles[i]); Microphonemanager.getinstance ().                PlayRecord (clip); Interval= (float) (GetTime (Audiofiles[i +1]) -GetTime (Audiofiles[i])).                TotalSeconds;                Debug.Log (interval); yield return Newwaitforseconds (interval); } microphonemanager.getinstance (). PlayRecord (Microphonemanager.getinstance (). Read (Audiofiles[audiofiles.length-1])            ); }         }
