TwitterWe hope we helped you solve the problem with the WAV file. If you do not know where you can download an application from our list, click on the link (this is the name of the program) - you will find more detailed information regarding the location from where you can download the secure installation version of the required application.
What else could be causing the problem?
There may be more reasons why you cannot open a WAV file (not only the absence of an appropriate application).
Firstly - the WAV file may be incorrectly linked (incompatible) with the installed application to maintain it. In this case, you need to change this link yourself. For this purpose, right-click on the WAV file you want to edit, click on the option "To open with" and then select the program you installed from the list. After doing this, the problems with opening the WAV file should completely disappear.
Secondly - the file you want to open may simply be damaged. Then, the best solution is to find a new version, or download it again from the same source as before (maybe for some reason in the previous session the download of the WAV file has not been completed and it cannot be opened properly).
Do you want to help?
If you have additional information about the WAV file extension, we would be grateful if you share it with the users of our site. Use the form provided and send us your information about the WAV file.
The most common reason for problems with opening the WAV file is simply the lack of appropriate applications installed on your computer. In this case, it is enough to find, download and install an application that serves files in the WAV format - such programs are available below.

hint
It should be noted that some encoded data from files that our computer does not read can sometimes be viewed in Notepad. This way we will read chunks of text or numbers - It's worth checking if this method also works for WAV files.
What if an app from the list has already been installed?
Often, an installed application should automatically link to a WAV file. If this did not happen, the WAV file can be successfully linked with the newly installed application manually. It is enough to right-click on the WAV file, and then select the "Select default program" option among the available ones. Then you need to select the "View" option and find your favorite application. The introduced changes must be approved with the "OK" option.

Why can't i open the WAV file?
Problems with the WAV files can also have a different background. Sometimes even installing WAV file serving software on your computer will not solve the problem. The reason for the inability to open, as well as work with the WAV file can also be:
Inconsistent WAV file links in registry entries
- corruption of the WAV file that we open
- WAV file infection (viruses)
- too little computer resource
- outdated drivers
- elimination of the WAV extension from the Windows registry
- incomplete installation of the program serving the WAV extension
The elimination of these problems should lead to free opening and working with WAV files. If the computer still has problems with the files, you need to use the help of an expert who will establish the exact cause.
My computer is not showing file extensions, what should I do?
In the standard Windows settings, a computer user does not see the WAV file extension. This can be successfully changed in the settings. It is enough to enter the "Control Panel" and select "Appearance and Personalization". Then you need to enter the "Folder Options", and open the "View". In the "View" tab there is an option "Hide extensions of known file types" - you must select this option and confirm the operation by pressing the "OK" button. At this point the extensions of all files, including WAV should appear sorted by file name.
What is WAV file? WAV (WAVE) is short for Waveform Audio File Format. WAV is an audio standard developed by Microsoft and IBM specifically for storing audio bitstream on computers. The WAV file used for raw and uncompressed audio, and it has grown to become a standard computer audio format for everything from system and game sounds to radio broadcasting.
Since WAV file is very popular now, it is not hard to find an audio player that is compatible with WAV file. In this article, we have listed the best WAV player we could find for you to play WAV player smoothly on PC / Mac.

About the library
TMRpcm - Arduino library for asynchronous playback of PCM / WAV files directly from SD card.
Uses Arduino standard SD library, SD card and output device (speaker, headphone, amplifier, etc.).
Supported Boards:
- all ATmega328 based boards: Arduino Uno, Nano, Duemilanove, etc .;
- mega boards: 1280, 2560, etc.
Features:
- Plays PCM / WAV directly from SD card.
- Main formats: WAV files, 8-bit, sampling rate 8-32 kHz, mono.
- Asynchronous Playback: Allows the code to run in the main loop of the program while the sound is playing.
- Operation on one timer: TIMER1 (Uno, Mega) or TIMER3, 4 or 5 (Mega).
- Push-pull output or connection of two speakers.
- Double up the sampling rate.
- Supported devices: Arduino Uno, Nano, Mega, etc.
Preparing audio files
Files are converted easily and easily:
- using iTunes:
- click Edit\u003e Preferences\u003e Import Settings;
- change the value in the drop-down list to WAV Encoder and Setting: Custom\u003e 16.000kHz to 32kHz, 8-bit, Mono;
- right click on any file in iTunes and select "Create WAV Version";
- with Audacity:
- Tracks\u003e Stereo Track to Mono;
- Project Rate (HZ)\u003e set 32000, 22050, 16000 or 11025;
- File\u003e Export\u003e Save as type: Other uncompressed files\u003e Options ...;
- select WAV, Unsigned 8 bit PCM.
Then use your computer to copy the file to the SD card.
Known limitations
This library puts a heavy load on the processor, and the code execution during playback will be slower than usual. The overhead of processing audio files can be reduced by using lower quality audio encoded at a lower sampling rate (with a minimum of 8 kHz).
Possible impact on other libraries that use interrupts. The isPlaying (), disable (), or noInterrupts () functions can be used to prevent parallel code execution.
The volume control allows for a good range of volume control, but distortion may occur at high volumes.
Loading
Also the project can be found on GitHub: link.

troubleshooting
If you have not been able to get this circuit to work, then below are two test sketches for troubleshooting. The code has been tested on Arduino Nano, Uno and Mega.
There is no need to connect buttons, files will be played automatically.
No need to connect a transistor, connect a small speaker or headphones directly to pin 9 of Arduino Nano board or pin 11 of Arduino Mega board.

Additional features
This library was intended for a simple and user-friendly use as a wav audio file player using standard Arduino libraries and playing files in the simplest wav format. Many additional features have been added as per user request and are included in pcmConfig.h to keep it simple.
Most advanced features require more RAM, more program memory and, in some cases, more processing power for playback. Some of them are still not fully debugged. Please keep this in mind when enabling these features.
See pcmConfig.h for setting the following parameters:
Custom definitions
The following parameters are configured in pcmConfig.h:
| Parameter | Description |
|---|---|
| #define buffSize 128 | Controls the size of two buffers (or four in MULTI mode). |
| #define DISABLE_SPEAKER2 | Turns off the default output of the second speaker for compatibility with other libraries (pin 10 on Uno). |
| #define ENABLE_MULTI | Turns on the play mode of several tracks (by default on one timer). |
| #define STEREO_OR_16BIT | Enables playback of stereo or 16-bit files. |
| #define MODE2 | Enables double timer mode for playing multiple tracks. Not available with TIMER2. |
| #define SDFAT | The SdFat library uses less program memory and RAM. See the SDFAT example included in this library. |
| #define HANDLE_TAGS | Skips tags in WAV files that contain metadata. |
| #define USE_TIMER2 | Uses 8-bit TIMER2 instead of 16-bit timers. |
| #define rampMega | Forced manual selection of PWM ramp on / off. |
| #define ENABLE_RF | Enables audio streaming via radio (NRF24L01 +). |
Second speaker / push-pull mode
This library by default outputs data to two timer outputs, although by default only one is fully enabled.
To enable, the auxiliary pin must be set to output, for example:
- Arduino Uno (one output): audio.speakerPin \u003d 9;
- Arduino Uno (push-pull output): audio.speakerPin \u003d 9; pinMode (10, OUTPUT);
To completely disable the second output, uncomment the #define DISABLE_SPEAKER2 line in pcmConfig.h.
Multi mode
Multi mode enables simultaneous playback of two tracks.
The functions of multi mode are slightly different from those of standard mode:
Audio.speakerPin2 \u003d 5; // Same action as standard mode, only used with 4-pin output audio.play ("sound.wav"); // Play output file 0 audio.play ("sound.wav", 30,1); // Play the file starting from the 30th second on output 1 audio.play ("sound.wav", 0); // play (filename, output 0 or 1) is defined by speakerpin or speakerpin2 audio.stopPlayback (0); // Can take output number 0 or 1 audio.isPlaying (0); // Can take output number 0 or 1 audio.setVolume (4,0); // Set the output volume to 0 audio.volume (0,1); // Decrease Output Volume 1
- default: uses the same timer and pins as in normal push-pull mode;
- MODE2: Uses two 16-bit timers and up to 4 pins.
Using:
- recommended sampling rate 16-20 kHz;
- the buffer size can be increased to improve performance;
- sounds played simultaneously must have the same sampling rates;
- to enable multi mode, uncomment the definition in pcmConfig.h;
- the audio.speakerPin2 variable must be set in 4-pin mode to select the additional timer / pin to be used.
Simplified modes:
Note: all 4-pin modes require a card with two or more 16-bit timers.
Stereo and 16-bit audio playback
These modes require additional resources and processing power, since double data must be read from the SD card. Mono tracks can be played back in stereo, but not vice versa.
In standard mode:
#define STEREO_OR_16BIT In this mode, stereo and 16-bit files are treated in the same way, with the first byte read to one output and the second byte to the other. This results in a stereo output on two speakers connected between the speaker terminal (s) and the chassis, or one 16-bit output using a resistor array. #define MODE2 In standard mode, MODE2 allows you to output stereo or 16-bit audio using two additional timer outputs. The timer and pins are indicated by the speakerPin2 variable. The timer push-pull pins must be manually set to output.
In Multi mode:
#define STEREO_OR_16BIT Enabling this option in conjunction with MULTI mode will play two stereo or 16-bit tracks on separate timer pins. This provides an output for four loudspeakers connected between the pin (s) and the chassis, or one 16-bit output for each track. #define MODE2 Enabling this option with MULTI mode and STEREO_OR_16BIT does not affect anything.
Using SDFAT
The SDFAT library can be used to reduce RAM and program memory usage and to improve performance. The files must be included in the sketch. See the example in the library archive.
Metadata (ID3v2.3 and LIST tags)
Functions have been added to read song, artist and album data from ID3v2.3 and LIST tags in WAV files.
Note: adding, modifying and editing metadata is supported by Audacity.
ListInfo Read LIST tags into a character buffer, returns the length of the tag. id3Info Read ID3 tags into a character buffer, returns the length of the tag. getInfo Searches for both tags and reads into a character buffer, returns the length of the tag. ID3 is searched first.
Tags for requests:
- 0 \u003d song title;
- 1 \u003d artist name;
- 2 \u003d album name.
Syntax:
Byte length \u003d audio.listInfo (
- Find only LIST information and print the song title via serial port. char info; audio.listInfo ("song.wav", info, 0); Serial.print (info); Serial.println (":");
- Find ID3v2.3 and LIST information and print song, artist and album information via serial port. char info; char * titles \u003d ("Now Playing:", "by:", "Album:"); for (int i \u003d 0; i<3; i++) { if(audio.getInfo("song1.wav",info,i) > 0) (Serial.print (titles [i]); Serial.println (info);)) audio.play ("song1.wav");
Using TIMER2
This library is often used with Uno, Nano, etc. with only one 16-bit timer. When TIMER1 is needed for other purposes, TIMER2 can be used for audio playback.
Speaker pins - on Uno, Nano, etc. only pin 3.
To enable the use of 8-bit TIMER2, uncomment the #define USE_TIMER2 line in the user definitions section.
Notes:
- this option is usually not the best solution;
- playback speed will be slightly different from using 16-bit timers;
- tIMER2 playback supports non-standard sampling rates: 31.4 kHz, 23.5 kHz and 15.7 kHz;
- upsampling is enabled by default and cannot be changed in this mode;
- recommended sampling rates of 24-32 kHz with a buffer size of 128.
PWM and rampMega option
In an effort to reduce the crackle noise generated by PWM, four main sources of the problem have been identified:
- enabling PWM / timers on Arduino;
- turning off PWM / timers on Arduino;
- difference in values \u200b\u200bbetween tracks;
- parsing non-audio data.
- 1 and 2. When testing on Arduino Duemianove and Mega boards, I found the need for different ramping methods on power on and off. Hopefully this will fix the problem on most other boards.
- 3. The ramp code does not change between tracks. When playing tracks with different sample rates, use the disable () function to disable timers between changes. See also # 4.
- 4. HANDLE_TAGS option is included in pcmConfig.h to ensure correct playback of wav files with included metadata (ID3 or LIST).
Easy digital creation of WAV files
These functions will generate standard WAV files. Raw data from analog inputs or other sensors can be written to a file to generate digital sound that can be played on any device that supports WAV files, or easily converted to other formats.
Note: more wav formats will be added in the future.
Syntax:
Audio.createWavTemplate (
Using:
See the example included in the library. Create a template file, then write data into it starting at 44 bytes. Use the finalizeWavTemplate command to add file size information before playback.
Notes: If the specified file exists, it will be overwritten on creation, but updated only on completion. These functions are called automatically when using write functions.
Sound recording
Audio recording is still under testing and may not perform as expected.
Functions:
StartRecording Start recording from the specified analog output. stopRecording Stop recording and finalize the wav file.
Pass-through mode - outputs sound to the speaker during recording.
Modes: 0 - normal / no; 1 - speaker is on; 2 - no recording, output only to the speaker.
Syntax:
Audio.startRecording (
Using:
- uncomment #define buffSize 128 and #define ENABLE_RECORDING in pcmConfig.h;
- start recording audio.startRecording ("sound.wav", 16000, A0);
- stop recording audio.stopRecording ("sound.wav");
Notes:
- the SdFat library is recommended for recording;
- minimum class 4 SD cards are recommended;
- may need to increase buffSize.
Have a problem opening a .WAV file? We collect information about file formats and can explain what WAV files are. Additionally, we recommend the programs that are most suitable for opening or converting such files.
What is the .WAV file format for?
File name extension .wav used primarily with files containing uncompressed audio data. This audio format was introduced by Microsoft. Uncompressed WAV files are supported by almost all programs capable of working with sound, which makes this format universal.
The organization of audio data in WAV files follows the RIFF specification, which allows the use of some tags that describe the content.
Uncompressed WAV files are considered "pure audio" because the sound has not been digitally processed. Therefore, they are a good choice for those who want to copy audio files without losing quality. Compared to MP3 files, uncompressed WAV files are significantly larger: each minute of recording takes about 10 MB in the case of a file .wav and only 1 MB in the case of .mp3 with medium settings.
Besides uncompressed audio, files .wav may also contain audio data compressed with one of the following codecs: ADPCM, MPEG Layer-3, Truespeech, Microsoft GSM 06.10, CELP, SBC. Compressed WAV files take up significantly less space and are less well supported by various applications.
