The Microsoft Media Foundation MP3 audio encoder is a Media Foundation Transform (MFT) that encodes MPEG-1 layer 3 (MP3) audio.
LAME is a high quality MPEG Audio Layer III (MP3) encoder licensed under the LGPL. Latest LAME release: v3.100 (October 2017) LAME development started around mid-1998. Mike Cheng started it as a patch against the 8hz-MP3 encoder sources. After some quality concerns raised by others, he decided to start from scratch based on the dist10 sources. Lame is a free MPEG audio layer III (MP3) encoder developed by Mike Cheng and Mark Taylor and designed Windows, Linux and Mac PC. Lame MP3 encoder features high quality encoder with remarkable conversion speed. Lame is considered the best when it comes to MP3 encoding with constant bitrate and variable bitrates (VBR and ABR). Older versions of Windows/old hardware. A compatibility table that includes old versions of Windows may be found on the Audacity wiki. Audacity 2.3.2 is believed to work correctly on Windows Vista, though please note that Vista is obsolete and no longer supported by Microsoft. More information about Audacity on Vista HERE.
Class Identifier
The class identifier (CLSID) of the MP3 encoder is CLSID_MP3ACMCodecWrapper, defined in the header file wmcodecdsp.h.
Media Types
The MP3 encoder supports the following media types. The output type must be set before the input type.
Output Types
Super mario world full game. Set the following attributes on the output media type.
| Attribute | Description | Remarks |
|---|---|---|
| MF_MT_MAJOR_TYPE | Major type. | Must be MFMediaType_Audio. |
| MF_MT_SUBTYPE | Audio subtype. | Must be MFAudioFormat_MP3. |
| MF_MT_AUDIO_AVG_BYTES_PER_SECOND | Bit rate of the encoded MP3 stream, in bytes per second. | The encoder supports all bit rates defined by the standard (32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256, or 320 Kbps). The default bit rates are 128 Kbps for mono and 320 Kbps for stereo. Use this attribute to specify the encoded bit rate. |
| MF_MT_AUDIO_NUM_CHANNELS | Number of channels. | The following values are supported:
|
| MF_MT_AUDIO_SAMPLES_PER_SECOND | Samples per second. | The following values are supported:
|
| MF_MT_USER_DATA | Additional codec data. | This attribute contains the 12 bytes of the MPEGLAYER3WAVEFORMAT structure that follow the wfx member of that structure. |
Alternatively, you can fill in an MPEGLAYER3WAVEFORMAT structure and call MFInitMediaTypeFromWaveFormatEx to convert the structure to a Media Foundation media type.

Input Types
Set the following attributes on the input media type.
| Attribute | Description | Remarks |
|---|---|---|
| MF_MT_MAJOR_TYPE | Major type. | Must be MFMediaType_Audio. |
| MF_MT_SUBTYPE | Subtype. | Must be MFAudioFormat_PCM. |
| MF_MT_AUDIO_BITS_PER_SAMPLE | Bits per sample. | Must be 16. |
| MF_MT_AUDIO_SAMPLES_PER_SECOND | Samples per second. | Must match the output type. |
| MF_MT_AUDIO_NUM_CHANNELS | Number of channels. | Must match the output type. |
The encoder supports only 16-bit integer PCM input. It does not support 32-bit floating point input.
Jun 01, 2017 To assign license key in vCenter Server 6.5. Click on Manage your Licenses in Getting Started Tab or Go to Licenses Tab. Click on + icon to Create New Licenses. Enter the vCenter Server 6.x Standard license key and press Enter to add a new line. Enter the vSphere 6.x Standard license key (For ESXi), and click Next. Label the license keys as per your convenient. Aug 07, 2019 The vSphere 6.5 and vSphere 6.7 product does not need new license keys. The existing 6.0 licenses will work and enable all the features of the software once upgraded. The ESXi 6.5 features are automatically enabled after you upgrade from ESXi 6.0. Oct 05, 2017 Licenses for VMware vSphere 6.5 can be obtained here: Free vSphere Hypervisor license: Download VMware vSphere Hypervisor for Free. All other licenses: Thomas-Krenn VMware vSphere 6 license configurator. Oct 05, 2017 When you go onto the VMware website to download esxi 6.5 u1 it gives u a free license number to enter on the esxi web interface after you have installed it. But it wasn't what I expected it only let's you create a VM with 8vcpu to get more you need to buy a license I bought one for £580 that includes 3 hosts and 1 vcenter server. License esxi 6.5. Nov 16, 2016 vSphere 6.5 has been released and as known from previous versions, VMware provides a free version of their Hypervisor ESXi for everyone again. The license key can be created for free at VMwares website. It has no expiration date. The binaries you will receive as 'Free Hypervisor' are 100% identical to the paid version.
Media Formats
The MPEG-1 and MPEG-2 standard defines 252 layer 3 audio formats. The MP3 encoder supports the standard with some exceptions, as well as some additional formats, as described below. Layer 3 is defined as:
| Channels | mono or stereo |
| MPEG-1 sample rates in kHz | 44.1, 48, 32 |
| MPEG-1 encoded bit rates in kbps | 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256, 320 |
| MPEG-2 sample rates in kHz | 8, 11.025, 12, 16, 22.05, 24 |
| MPEG-2 encoded bit rates in kbps | 8, 16, 24, 32, 40, 48, 56, 64, 80, 96, 112, 144, 160 |
The MP3 encoder also supports the following formats.
| Sample Rate | Bit Rate | Channel Number |
|---|---|---|
| 8000 | 18000, 20000 | 2 |
| 11025 | 18000, 20000 | 1 or 2 |
| 12000 | 18000, 20000 | 1 or 2 |
| 16000 | 18000, 20000 | 1 |
| 32000 | 144000 | 1 or 2 |
| 44100 | 144000 | 1 or 2 |
| 48000 | 144000 | 1 or 2 |
The MP3 encoder does not support the following formats defined by the standard.
